how long does it take to make a lab-grown diamond

The Chinese Academy of Sciences grows diamonds! It only takes a week to grow a 1-carat diamond, which is as pure as a natural diamond.

The Chinese Academy of Sciences "grows" diamonds, which can "grow" 1 carat in a week. According to experts, diamonds are grown in the same way as grains, which require seeds and nutrients, and the seeds are natural diamonds. In addition, methane gas is needed. With the energy, the methane forms a carbon plasma, which, like dust, slowly deposits on natural diamonds in the air, bit by bit.

Inside the laboratory of the Ningbo Institute of Materials of the Chinese Academy of Sciences, experts from the "Functional Carbon Materials" team are examining the raw materials used to make diamonds.

Carbon atoms split off from the methane gas are deposited on the "seed diamond" and "grow" at a rate of 0.007mm per hour. In a laboratory setting, a one-carat diamond can be "grown" in less than a week.

1-carat diamond

It only takes a week to grow a 1-carat diamond in the laboratory environment of the Chinese Academy of Sciences. It is as strong and pure as a natural diamond but costs only one-sixth as much. Would you buy cheap, nice rhinestones?

If a scalpel made of this new material is used, it will be sharper and last longer.

One-carat diamonds because of different technology prices are different, up and the difference can reach 200,000-200,000 yuan. If the low standard is used, the cost of a diamond cultivated by CAS may be more than 3,300 yuan and less than 10,000 yuan, so the price is quite cheap.

In addition to making diamond jewelry, the technology could also be used to make precision instruments for lidar. For example, surgical knives made of this material will be sharper and last longer.

Chemical vapor deposition (CVD) is a chemical technique used to produce high-purity solid materials. Typically, the substrate is exposed to the gas of the feedstock, and the substrate surface undergoes a chemical reaction to produce a thin film. Mainly used in the semiconductor industry to produce silicon, silicon oxide, carbon fiber, carbon nanotubes, silicon carbide, silicon nitride, and other materials. CVD is also commonly used to produce synthetic diamonds.

According to the report, "seed" diamond raw materials are natural diamond seed gold flakes and methane gas.
