But her expression had betrayed her, and Quilting Lu could see it. She must have thought of a follow-up method, must, must...
"Haitang, it's not easy for me. I'm just a small minister of the Ministry of War. Just help me..." Zilu's voice of pinching his throat made everyone get goosebumps...
You are the minister of war, the young prince, and the emperor’s favorite and most relied-upon celebrity. It’s not easy for you. How can we, the working people, survive...
"Okay, let me tell you, if this thing is gone, you can still use it to replace it." Haitang took out an object from the package, which was also gray, but not as bright as molybdenum.
This was also cut from the mine just now.
"I've seen this before. It's inside, and I saw it too." Mr. Zhang recognized it at a glance.
Zilu pinched the thing, it was hard, cool and light gray.
"What about this again?" Zilu also became eager to learn.
Haitang wanted to say, this is tungsten, but the word molybdenum just now made them dizzy, because there was no such word in this era.
Haitang thought for a while and said, "This is called a wolf."
Why is it called wolf?
Because the chemical symbol for tungsten is the abbreviation of , the first four private placement wolves happen to be wolves.
"What a good name. I love this wolf, but I am afraid of that wolf..." Mr. Zhang thought of the wild wolf from Lianshui Mountain.
At least this wolf won't bite!
When holding this piece of tungsten, who would have thought that it was this thing that made officers at all levels in Nazi Germany so eager for it that they even exchanged it for gold.
It also played a dark role like a wolf in World War II.
"Then what's the difference between the two?" Zilu asked again.
"When wolf is added to steel, the melting point is higher, and the weapons it creates are harder than molybdenum," Haitang said.
Tungsten is the hardest metal known. Adding a little bit to steel can create perfect drill bits and saw bits.
If tungsten is used as the warhead, even a smaller missile, a kinetic energy armor-piercing missile, can destroy a large tank. Note that it is not penetration, but complete destruction.
Looking at the periodic table of elements, it is easier to understand why tungsten is a better metal additive.
Tungsten has similar properties to molybdenum, but it has more electrons than molybdenum, and its melting point is as high as 3426.67 degrees Celsius. This is also a test for the smelting technology of this era.
In addition, tungsten atoms are heavier than molybdenum atoms, so they can better fix iron atoms. In other words, as long as the smelting technology can reach a certain temperature, tungsten is an excellent substitute for molybdenum.
"I will ask the foundry office to study how to increase the temperature. It should be no problem. Great, Haitang. I didn't expect that there are two kinds of metal additives in a mine. God is really helping my country. Haitang, that is the fairy descending to the earth. I
I really don’t know how to thank you!" Zilu looked very excited, and even used the terms Haitang used when he spoke.
"The young prince can be compared to a fairy descending to earth. The girl is really flattered." Haitang said with a hearty smile.
Everyone laughed...
What Haitang didn’t mention is that in addition to tungsten, there is also a metal additive, which is scandium. However, it is not found in this mine, and it may not be found in other mines. The tungsten and molybdenum are enough for Zilu.
Scandium is used in modern times to make aluminum baseball bats and bicycle frames, and in the 1980s it helped the Soviet Union build light helicopters.
