If it hadn't been for Gao Qijing's acquisition of the largest sapphire in the country of Ska this time, Chen Wenzhe would never have been able to remember the largest man-made sapphire.
However, when I think about it now, are the gems in this world real or fake?
Just like artificial diamonds, as long as they are beautiful enough, they are not diamonds anymore?
Thinking about it this way, even if a sapphire is made with higher technology and better quality than diamonds, it would not be beautiful even if it is man-made?
You know, their internal structures are the same.
Therefore, it is still a very high achievement for the world's largest single sapphire to be born in China.
It is not a discovery but a birth, which has a very high technical content.
Of course, it is not the largest one, because its weight is not heavier than the one from Ska, it seems to be only 450 kilograms.
Why is the 310 kilogram sapphire just now said to be the best among natural corundums?
It's because there are other types of firsts.
For example, this is the world's highest weight and largest single artificial sapphire crystal.
It was born in the production workshop, with a weight class of 450 kilograms, which has increased the previous world record of 350 kilograms held by Russia by 100 kilograms.
Speaking of gems, the first thing people think of must be jewelry.
In fact, these are not the most important things for modern people.
Because as an important raw material in the field of high-tech production, artificial sapphire has long been integrated into people's daily lives.
From smartphone cameras, touch screens, LED lights, to state-of-the-art equipment, high-intensity lasers, optical components of astronomical observation systems, artificial sapphires are everywhere.
Since the new century, the demand and output value of sapphire originals in developed countries and regions such as the United States, Europe, and Neon have reached astronomical figures.
And our country’s sapphire production and manufacturing industry has just started.
Chen Wenzhe was very interested in being able to artificially create such a large sapphire.
When he heard that it was an artificial gemstone, he gave up and didn't care.
Now think about it, what happened to artificial gemstones? Aren’t they beautiful?
As long as it's big enough, can he directly use sapphire to carve anything he wants?
Just like using agate to make agate teapots, tea bowls and other works, sapphire works should be more beautiful, right?
Since sapphires can be made, can rubies be made artificially?
Thinking of this, Chen Wenzhe became very interested in the giant artificial sapphire that he had never seen before.
As long as he gets that treasure, he can trace back all the manufacturing techniques through it.
No, the domestic production technology seems to be a bit behind, so if he purchases a batch of high-quality artificial sapphires from abroad, can he get better technology?
With this idea in mind, Chen Wenzhe asked Gao Qijing.
Since he is involved in the gem industry, he must have some knowledge about the manufacture of artificial sapphires.
Sure enough, when he asked, he found that he had really asked the right person.
Since 2000, my country has begun to carry out all-round development of sapphire growth technology.
The production method is based on the temperature gradient method to create products.
Although in terms of quality, it can fully meet the requirements of the military and optoelectronic industries, in terms of mass production, it has been unable to get out of the laboratory for a long time.
It was not until 10 years later that good news came frequently about things like this.
In April 2011, a technology company in Qilu made a formal breakthrough in the LED sapphire substrate wafer project, and the finished product was officially put into production.
Within 3 years, they expanded production capacity to 1.8 million pieces.
This marks that my country's LED sapphire chips have broken the foreign technology blockade and formed large-scale production.
In June of the same year, a 100-kilogram artificial sapphire crystal was born in Sujiang Province.
This makes the supply of high-quality materials for my country's rapidly growing LED industry a reality.
This once again breaks the passive situation of my country's sapphire crystal growth and substrate manufacturing market's long-term dependence on imports.
In April 2016, the first artificial 120-kilogram sapphire crystal was launched in China’s “Optics Valley”.
This marks the official birth of the smartphone industry, with locally made sapphire touch screens.
At that time, the chief engineer of the R&D project proudly said: "We supply lens covers and home buttons for Apple phones. In addition to targeting optical applications, we will also focus on electronic applications such as smartphone panels."
Only then did Chen Wenzhe realize that sapphire actually had so many applications on mobile phones.
At this time, he was even more convinced that he must master this technology.
Not to mention other things, with enough red and sapphires, there is no shortage of raw materials for making gem bonsai.
The more he learned, the more proud Chen Wenzhe became of the country's achievements in recent years.
No wonder many people abroad now look envious, jealous and hateful towards Chinese people.
If you don’t go abroad, you won’t feel this deeply.
Chen Wenzhe, who has been abroad for a year, can be said to have deep feelings about this.
It used to be that when people went abroad to Southeast Asia, they were mainland Chinese, and now they are rich people.
Although there are more robberies against Chinese people, it can be seen from now on that our country has really become stronger.
Looking at Sapphire's manufacturing among people, there are really many achievements. It can be said that this series of news in the past ten years is enough to excite the Chinese people.
However, from a fundamental point of view, sapphire's "Made in China" has not completely overcome the adversity, and there are still problems of one kind or another.
For example, product production equipment and production processes are still largely dependent on imports, resulting in a lack of say in production costs and product prices;
More importantly, our country's production capacity and product size cannot yet meet the comprehensive needs of national defense technology and important national weapons.
This problem had not been solved until two or three years ago.
For example, in early 2017, Russia proudly announced to the world that the world's largest 350-kilogram artificial sapphire was born in the country.
In the final analysis, our lack of international voice in the industry is due to the lack of core production technology, a set of production technology that is completely our own!
Therefore, a few years later, the emergence of this sapphire giant not only represents its own value, but also competes for international voice.
Now, this artificial sapphire weighing 450 kilograms still stands in front of a display cabinet in Mongolia Province.
Therefore, the one Chen Wenzhe got was not the first one, but it was indeed the largest one produced in China.
This one was made during a process test, and its size is about the same as the first one.
Being able to produce two huge sapphires with high purity in a row is enough to show the maturity of the technology.
It is not an accident, but truly mastering the core technology, which is the most important thing.
With this technology, it will be of great help to the domestic smartphone industry.
