Lab-grown diamonds are widely used in high-tech fields. China’s production capacity is highly concentrated.
Grown diamonds, also known as artificial diamonds, man-made diamonds, synthetic diamonds, grown diamonds, and laboratory diamonds, are crystals created in the laboratory through high-temperature and high-pressure methods and chemical vapor deposition methods. The synthesis technology is relatively difficult and has the same properties as natural diamonds. appearance, chemical composition, physical properties and crystal structure.
From an identification perspective, the carat weight, clarity, cut, and color of lab-grown diamonds can already be identified and graded using natural diamond standards. From a price perspective, lab-grown diamonds are of high quality and low in price, with the market price being only one-third of natural diamonds. Natural diamonds have limited reserves and are non-renewable resources. They often take hundreds of millions of years to form. Cultivated diamonds can be made in just a few days. As the demand for diamonds continues to increase and the supply of natural diamonds decreases, they serve as a perfect substitute. With their excellent properties, lab-grown diamonds have filled the market gap of natural diamonds, and the industry’s prosperity continues to rise.
According to the “In-depth Market Research and Development Prospects Forecast Report of China’s Lab-grown Diamond Industry 2023-2028” released by the Industrial Research Center, cultivation In the early days of diamond research and development, it was mainly used in industrial fields such as telecommunications, abrasive materials, laser optics, etc. With the rapid development of modern industry and the continuous advancement of science and technology, the quality of cultivated diamonds has been upgraded and has been more widely used. Among them, high and new technologies are its important applications. one of the fields. As the key to the future high-tech revolution, cultured diamonds are currently mainly used in semiconductors and electronic devices, cultured diamond detectors, optical materials, ultra-precision processing, etc.
From the perspective of semiconductors and electronic devices, existing semiconductor materials have great limitations. Silicon materials are limited by their own physical properties and cannot be widely used in high-frequency power devices; second-generation semiconductor materials such as indium phosphide and gallium arsenide It can produce high-frequency, high-speed, and high-power devices, but it is expensive, toxic, and has great application limitations. As a prominent material of the third generation of semiconductor materials, diamond has the properties of resistance to high temperatures, high pressures, radiation, and high frequencies, and is considered the “ultimate semiconductor material.” Lab-grown diamonds can perfectly replace diamonds and have great potential in semiconductor and electronic device applications.
From the perspective of cultured diamond detectors, cultured diamonds can adapt well to harsh radiation environments, are less affected by stray light, and have no special requirements for operating temperature. They are excellent materials for making detectors. From the perspective of optical materials, cultured diamond has properties such as high thermal conductivity, high hardness, and high transmittance, making it an ideal optical material. From the perspective of ultra-precision processing, ultra-precision cutting instruments made of cultivated diamonds can theoretically produce atomic-size sharpness and flatness, and are widely used in nuclear reactors, precision instruments, aerospace and other fields.
Industry analysts said that in the field of cultivated diamonds, my country has developed rapidly and accounts for more than 50% of the global cultivated diamond production capacity. Due to the technical difficulty of cultivating diamonds, high industry barriers, and relatively concentrated production capacity, 80% of my country’s cultivated diamond production capacity comes from Henan. Cultivated diamond companies in the province, such as Zhongnan Diamond, Yellow River Tornado, Power Diamond, and Yu Diamond, have developed rapidly and have become leading domestic companies. .
