All OUR RING CAN PASS THE DIAMOND TESTER
One is the chemical gas phase deposition method, which is called CVD in English.
This method is more dexterous and is a way of making diamonds in a high pressure device. Specifically, in an autoclave the size of a dishwasher, chemical gas phase deposition is used to heat natural gas and hydrogen, and then a kind of carbonized plasma will be produced, and the plasma will then fall on the bottom of the autoclave like raindrops. On the carbonized substrate layer. The plasma accumulates more and more, and gradually hardens, finally forming a crystal like diamond, pure and clear.
After decades of experiments, scientists can finally "plant" artificial diamonds comparable to the most precious De Beers diamond.
Single crystal diamonds larger than 2 carats can be "seeded" soon. Scientists have successfully mastered the method of making 10-carat single crystal diamonds. The most powerful thing is that this kind of diamond even surpasses real mineral diamonds in color and purity. In 10 years, man-made diamonds will become cheaper and cheaper. In 2011, the first diamond semiconductor will be available on the market.
The influence of CVD (Chemical Vapor Deposition) diamond
In the past, expensive diamonds, which were claimed to take millions of years to crystallize, can be manufactured in less than a week in the laboratory, subverting the common sense of values of diamonds.
In the past, diamonds were mostly used as jewelry because of their high prices. Once high-quality diamonds can be produced cheaply, their application value will quickly spread to various fields.
Experts predict that the most important invention in the 21st century will be diamonds that will grow up. One day, cheap and good-quality diamonds will replace the role of silicon in semiconductors and enable human technology to enter another world.
After diamonds are mass-produced, they can be more affordable and develop more diversified functions. Diamond has high hardness, excellent thermal conductivity, cutting and abrasive properties, and can be used in medical and electronic components.
