Osmium and a certain amount of iridium can be used to make an osmium-iridium alloy. For example, the small silver-white dot on the nib of some high-end gold pens is an osmium-iridium alloy. Osmium-iridium alloy is hard and wear-resistant, and can be used to make clocks and important instruments.
Bearings have a long service life.
Of course, in addition to being used to make these ordinary items, osmium can also be combined with gold to make osmium gold jewelry.
"This is very valuable." Chen Qing asked after the diving guide was sent away and the brothers sat down.
Han Kongque said with a smile: "It's worth about 100 yuan per gram!"
"This thing is so heavy and so expensive?" Gu Lie said in shock. The density of osmium ore is high. A small piece weighs dozens of grams. One gram is 100 yuan, which is several thousand yuan.
Han Kongque said: "It has a wide range of uses! So the price is really not expensive."
"Is osmium gold the most precious gold?" Yuan Peng also asked.
"No!" Song Min said.
"If not, which one is the most valuable? Is the higher the density, the more valuable?" Gu Lie asked.
Han Kongque said: "If you ask which gold alloy is the most expensive, then no matter whether you mix it with 'osmium' or 'iridium', it is not as expensive as pure gold, which is pure gold.
If you are asking which metal is the most expensive, then it has to be 'californium'. Its value is 1 million to 2 billion US dollars per gram. To be precise, the less it is, the harder it is to extract and the more expensive it is if it is not easy to preserve.'
Calfium is a material specially used for nuclear research, so it’s surprising that it’s not expensive.”
"I didn't expect that you would earn wealth that many people would never get in a lifetime." Song Min said with emotion, Han Peacock is a miracle!
Han Peacock smiled and said: "What have you been doing in the past half month? Have you found the black coral?"
To this day, Han Peacock is still obsessed with black coral.
Gu Lie said: "I found two nautiluses and have sent people to Peacock Island. Without you, it is only possible to feed the nautiluses there."
"Ah! You found the Nautilus?" Han Kongque was a little surprised. When did Gu Lie become so powerful?
"Don't listen to his bragging. It was Shui Bao who found it. Shui Bao is the latest bodyguard mobilized. They are all water power users. Otherwise, how dare he go to the deep sea just by Gu Lie?" Song Min hit her husband.
"Haha, let me tell you, you really know how to take credit from others." Han Peacock sneered.
Gu Lie said dissatisfied: "I went into the water with you, and I picked up the nautilus with my own hands. Why do you say I don't have any credit?"
"Okay, you are awesome. You have made a contribution this time. What do you want? I have found a large amount of ore. You can have whatever you want." Han Kongque said with a smile.
Gu Lie said happily: "Blue square stone, I have long noticed that Song Min's eyes are filled with stars, so I will give that blue square stone to Song Min."
Song Min rolled her eyes at Gu Lie and gave him a knowing look.
Chen Qing said with a smile: "I want that kind of rhodolite, the most beautiful one."
Yuan Peng thought for a while and said: "The stone is not bad, I want this one."
Han Peacock laughed and said, "Okay, you can choose whatever you want."
After saying that, Han Peacock took out some very high-quality ores, including blue ashlar, sphene, rhodolite, and other minerals of various colors. As long as they were very beautiful and reached gem level, Han Peacock would not hesitate.
Being stingy, I put them all out for them to choose from.
"Is it true that no black coral was found?" Han Peacock asked again.
If it was just Chen Qing and the others who were diving, Han Peacock would never ask again, but with the help of some water power users, it shouldn't be difficult to find the black coral.
"See if it's like this?" At this moment, Gu Lie took out a piece of coral. It was dark brown, and it was really black coral.
Looking at the backpack beside Gu Lie, Han Kongque knew that they should have found a lot of black coral.
This kind of coral that looks like a black tree is black coral.
Black coral, also known as sea willow, commonly known as sea iron tree, is a special species of gorgonian coral.
Corals of the order Black Coral mainly live in the warm waters of the Western Pacific, in the waters south and north of Bendao Island, and in the Hawaiian Islands, there are also black corals. This time, the Korean peacock came here just for the black corals.
of.
However, now that Han Kongque took a closer look at the coral Gu Lie took out, he couldn't help but feel a little disappointed. It was obviously a shallow-sea coral. Its texture was sparse and could not reach gem quality at all.
"There should be a lot of corals like this, right? But collecting them shouldn't be allowed here, right?" Han Peacock said.
Gu Lie said with a smile: "I only collected this one plant. It has no value, so naturally I don't need to collect too many."
"You know it's worthless, right?" Han Kongque rolled his eyes.
In fact, black corals are not difficult to find. They usually grow at the bottom of darker and more hidden reefs or cliffs. They are more common in water depths below 20 meters. However, only black corals in deep water areas can reach gem quality.
Black coral is similar to red coral. The quality in shallow water is very poor. The black coral group has a black central axial skeleton, densely branched but irregularly distributed, and looks like a tree.
Therefore, it is also called sea tree or sea pine. The coral polyps are yellow-green or milky white and are densely distributed on the branches.
Black coral is brown-black, composed of shell keratin, extremely tough, with a small hardness and waxy luster.
Gem-quality black coral has a contracted tree ring-like structure in its cross section. It is tough and corrosion-resistant. It is known as "iron wood" and is a valuable raw material for carving precious handicrafts.
It is full of treasures and has a wide range of uses. Coastal artists are good at taking advantage of the sea willow's strange shape, beautiful color, hardness and corrosion resistance, and delicate wood to carve out various exquisite and exquisite pipes through pruning, planing, grinding, filing, drilling, etc.
, bracelets, tea cups, necklaces, rings and other art treasures.
The coral used as gem material is exactly and only the skeleton of the coral, that is, the coral body.
Due to the growth pattern and structure of coral bodies, most coral bodies are often hollow, and the bones are not suitable for processing and polishing, because not all coral bodies can be used as gemstone materials.
Only those corals with dense and uniform texture and good polishing properties can be classified as gemstones.
Therefore, although there are many types of corals, there are not many types that can be used as gemstones.
Although hard corals are important reef-building corals, the bones of these corals are not suitable as gemstone materials.
The vast majority of corals used in gemstones are octagonal corals (also known as octagonal corals). They mostly live in tropical or subtropical coastal areas or sub-littoral areas. Some species can also live in seawater more than 4,000 meters deep.
Although they had expectations, it was still dangerous for Chen Qing and the others to dive into the four-thousand-meter-deep sea, so even if there was no gem-quality black coral, Han Peacock was not particularly disappointed.
"Forget it if you don't have it, it will be the same when we buy some ancient black coral products." Han Kongque said.
Chen Rui said with a half-smile: "In ancient times, were there black coral products? Gem-quality ones?"
"Of course, black coral is tough, durable, and lustrous, so it can be processed into various crafts. The crafts that can be used for them take at least 2 to 3 hundred years, such as bracelets, bonsai, flowers, birds, insects, and fish, etc.
In 1958, an ancient tomb from the Song Dynasty was excavated on Dongshan Island, Fujian Province. Some bracelets, rings and wine glasses made of black horn coral were found from the coffin hub. These items were all intact, which shows the toughness and corrosion resistance of black horn coral.
." Han Peacock said.
Chen Rui smiled and said: "Then you don't have to bother, just take a look at this black coral. Are you sure this is black coral?"
As Chen Rui laughed, she took out a large coral tree from her backpack, but this coral tree was golden, not black.
"Tawny? It's really black coral. Most of these black horned corals come from Japan. I didn't expect that they can be found in Hawaii?" Han Peacock picked up this golden coral with a surprised look on his face and examined it.
Just by weighing it a little, Han Peacock knew that this coral was definitely at the gem level. Although black coral was the lightest among corals, this black coral was obviously much heavier than the previous one.
"It does look very similar to Japanese black horn coral. You should have checked the information, right?" Han Peacock looked at Chen Rui and others with a smile.
Chen Rui said: "We asked professionals to identify it, otherwise we would have thought it was gold coral!"
"It is indeed not gold coral. The gold coral in Hawaii is not like this." Han Peacock nodded.
The golden coral is different from the black horn coral. The Japanese black horn coral has a group like willow branches in the masson pine. The rachis is horny, the branches are compound pinnate, dark brown and yellowish brown, with multiple branches, and the front edges of the small branches are alternately arranged.
The barbules are hard and dense.
The barbules are divided into 1-5 levels of finer and shorter bristly secondary barbs, which protrude from the front or front side of the barbules to form a flat surface.
In this way, a multi-layered barb plane is formed on the branches. The thorns on the barbs have thin tips, are conical, and have 8 longitudinal lobes. They turn golden yellow after the group emerges from the water.
The Hawaiian Islands produce diving gold corals, so when they first come out of the water, they are considered to be gold corals. However, the gold corals in Hawaii are all diving gold corals and cannot reach gem quality.
Golden coral is a gem coral species that grows in the Pacific Ocean. Its biological classification belongs to the subclass Octoporaphylla and the family Golden Coral. The axial skeleton can be golden or brown, and can have special optics such as iridescence and color change.
Phenomenon.
Golden corals can be divided into two species: deep-water golden corals and shallow-water golden corals according to their growth environment.
Deep-water golden coral is found in the waters of Midway Island in the Pacific Ocean at a depth of about 900 meters to 2,500 meters.
Shallow-water golden coral grows in the waters southwest of Maui and Bend Island in the Hawaiian Islands at a depth of about 350 to 600 meters.
This black horned coral looks very much like a golden coral. It has a dense texture and is not comparable to that of diving corals.
And Chen Qing and others must have collected it from the deep sea. If it is regarded as an ordinary shallow water golden coral, they will definitely not agree. Even if they do not understand what golden coral is and what black horned coral is, they will always
Know what is shallow water and what is deep sea.(~^~)
