The powder integrated block is mainly used to synthesize high quality diamond. It is well known that the specific surface area of ​​powder catalyst and powdered graphite is much larger than that of sheet-like catalyst and flake graphite, and the contact area between the two is large, so that the synthetic diamond productivity is greatly improved. Due to the uniform distribution of powder catalyst and graphite in the reaction chamber, diamond nucleation is in a three-dimensionally uniform space. As long as the proper pressure and temperature conditions are provided, the single crystal can grow uniformly in all directions, and the crystal form of diamond is intact. The rate can be greatly improved, and the proportion of high-quality diamonds is significantly increased. Special activation treatment of powder core, powder graphite and rare earth additive pressed core blank is beneficial to the diamond growth process, which is beneficial to improve the color of diamond and improve the thermal stability of diamond.
Synthetic diamond is a kind of functional material with high hardness and excellent thermal conductivity obtained under high temperature and high pressure. Its unique wear resistance is irreplaceable by other materials. It is widely used in machinery, electronics, chemical industry and aerospace. , minerals, optics, medical, acoustics, communications, building materials, furniture and other fields. The popularity of diamonds and their products will bring human material civilization to the peak. Its excellent physical and chemical properties make it the basic material of modern industry. Diamond consumption, especially high-quality diamond consumption, has become a measure of a country's industrial level. Important sign.
