Technical Method And Application of Synthetic Diamond Grit

The development of synthetic diamond grit is the use of high pressure, high temperature technology to convert graphite into diamond. The method of synthesizing diamond can be divided into the following types:

1. The static pressure method includes a static pressure catalyst method, a static pressure direct conversion method, and a seed catalyst method.

2. The dynamic pressure method includes an explosion method and a liquid discharge method, which are directly converted into hexagonal diamond.

3. Methods for growing diamonds in the metastable region include chemical vapor deposition, liquid phase epitaxy, gas-liquid-solid phase emulsion growth, and atmospheric pressure normal temperature synthesis.

Main use of synthetic diamond grit: It is used for wire cutting of 3-12 inch single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystal. It is used as an engineering processing material for the solar photovoltaic industry, the semiconductor industry, and the piezoelectric crystal industry. It is used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear, catalyst carrier and other fields.
