This giant artificial sapphire is completely transparent and has no bubbles.
When you touch it with your hands, you can also feel the unique texture of the gemstone.
This is currently the highest weight and largest single artificial sapphire in the world, based on the in-vivo production technology.
The soaking method is currently the mainstream method for producing artificial sapphire in the world. It is also the most important production process for countries around the world to devote themselves to technological research and increase investment in technology research and development.
The principle is to first heat the alumina raw material to the melting point to form a molten soup, and then use the seed rod to contact the surface of the molten soup.
Then, at the solid-liquid interface between the seed crystal rod and the molten soup, a single crystal with the same crystal structure as the seed crystal begins to grow.
The seed crystal pulls upward at an extremely slow speed, and finally solidifies into a single crystal.
This is a relatively long production process, which has extremely high tests and extremely demanding requirements on the control of furnace temperature and the coordinated application of the production system.
Therefore, the technical requirements for producing 450-kg products are not at the same level as those for 200-kg or 350-kg products, and there is a qualitative difference.
For Chen Wenzhe, this kind of craft seems not unfamiliar at all, and can even be said to be very familiar.
He felt, isn't this just like making porcelain?
The difference is that the crystals grow.
However, as long as you know how to stay away from it, for Chen Wenzhe, this kind of artificial sapphire craft is really not too difficult.
Especially the process of generating sapphire. Isn't this a kiln firing?
He also has to control the furnace temperature, and in this regard, he has almost reached the level of a grand master.
Therefore, at this time, he was really interested in generating sapphires.
However, domestic technological leaps are too fast. A series of achievements can be understood after seeing Chen Wenzhe's fireworks.
Only then did he realize that he had underestimated the scientists in the country.
Also, he is a plagiarist, but he still dares to think about going abroad to acquire technology to develop domestic technology?
Now that the country has stood up and the people have stood up even more, naturally, scientists have stood up further.
Therefore, if he wants to enter the industry, he may not be as good as those domestic scientists.
Mainly domestic scientists are really awesome.
Of course, this is also because I was stimulated by the oppression from foreign countries.
Therefore, after mass production of 100kg and 250kg artificial sapphires was achieved, the R&D team did not stop innovating.
In 2017, not long after Jinghuan Electronics' 300-kilogram sapphire reached production conditions, a Russian company set a world record of 350 kilograms, which stimulated the R&D team.
When you are stimulated, you must accept the challenge and compete.
If you want to compete with scientific research teams from various countries, you have to hold on;
One is our domestic industry and enterprises themselves, which indeed have a great desire for new core technologies. This is the biggest driving force for our research and development!
As a result, "Full-automatic sapphire crystal growth technology using the bubble method and ultra-large-size sapphire crystal growth technology" have gradually taken shape in domestic laboratories.
Our core technology must be independently developed automated production equipment, thermal production design theory and micro-process applications.
In other words, everything from raw material selection, processing, and production is made in China.
The birth of this artificial sapphire giant will gradually change the production order of the world's artificial sapphire industry. We must gain international say based on this!
And new technologies will definitely open up a new situation in the industry.
In recent years, the LED industry has developed rapidly around the world.
Its products are widely used in lighting and blue light laser fields.
Especially when used in liquid crystal displays, the market is expanding rapidly.
Almost 100% of laptop computers and more than 50% of LCD TVs use LED products.
The growth of artificial sapphire crystals and the manufacturing of substrates are at the forefront of the LED industry chain.
This is the link with the largest investment and the highest technical barriers in the industry.
At the same time, it is also the section with the highest added value. The premise is that you must have your own core technology!
Due to our long-term and large-scale reliance on imported production equipment and production technology, our country has never been able to take the initiative to dominate and influence international commodity prices.
Therefore, domestic production companies are also suppressed. While the industry is prosperous, a large amount of profits are given overseas.
If technology-based enterprises want to reduce costs and pursue profits, they have no other way out but to rely on technology.
The success of the trial production of Big Mac artificial sapphire is not only reflected in its size, but also in its quality.
The new product can be applied to LED 4-inch ingots with an effective length of more than 4550 mm.
This standard, derived from crystals of such large size, is already the best proof.
As the technical threshold is getting higher and higher, domestic sapphire production companies are also facing a reshuffle process of survival of the fittest.
Most of the hundreds of companies that used to exist have now ceased production or switched production.
This is an inevitable requirement of the market and is the result of high-precision technology.
Currently, domestic scientists are working hard to achieve mass production of ultra-large size crystals.
For enterprises, the new technology can achieve a new production situation in which the input volume is increased by 2.5 times, other costs remain unchanged, and the output is increased by 5 times;
For the country, the independent research and development and production of oversized crystals will provide the greatest and safest guarantee, whether in the civilian or military fields.
"Artificial sapphire is really important!"
Chen Wenzhe glanced at Gao Qijing with a very strange expression. He always felt that this guy was leading the conversation.
"It's very important!" The look on Gao Qijing's face was a little weird!
If it wasn't important, why would he lead the topic like this?
Are you doing all this just to arouse Chen Wenzhe's interest?
Gao Qijing now also understands some of Chen Wenzhe's technical level.
Although most of the techniques now are used in firing porcelain, he felt that his little boss should also be able to learn how to make artificial sapphires.
It's true that this person learns new technologies very quickly.
There is no way, since it has fallen into the eyes of the country, some things about Chen Wenzhe cannot be kept secret.
Therefore, a series of high imitations he has recently produced have been thoroughly studied.
He has never been exposed to it, but as long as he wants, he can bake it quickly. Who can match this kind of learning ability?
Therefore, the artificial sapphire this time is just a little test!
Chen Wenzhe naturally didn't know these things, but he was really interested in artificial sapphires.
He turned around, looked at Gao Qijing and said with a smile: "How did Li Jinli buy this artificial sapphire? Forget it, I'll ask again when I get back. No matter what, the one he bought can't be compared to your two.
