Tianyou single crystal superhard materials include high temperature and high pressure method single crystal diamond, CVD method single crystal diamond and cubic boron nitride, etc. The high temperature and high pressure method single crystal diamond is to place the assembled pyroxylite synthetic block in the six-sided top press chamber, and through high temperature and high pressure, the single crystal epitaxial growth is carried out. After taking out the synthetic block and refining, the single crystal is selected and graded. High temperature and high pressure single crystal diamond is characterized by high hardness and orderly lattice arrangement, with the mass production of large six-sided top press and the development of technology, the size of high temperature and high pressure single crystal diamond is becoming larger and larger.

Polycrystalline superhard materials including diamond polycrystal and cubic boron nitride polycrystal are sintered with diamond micropowder and cubic boron nitride micropowder as the main raw materials under high temperature and high pressure after adding a binder; Although the hardness and heat resistance of the polycrystalline superhard material are slightly poor, its area is larger and its wear resistance is better.

CVD diamond uses methane and hydrogen as the precursor, under high temperature (about 1000℃), atmospheric pressure (1 atmospheric pressure) or low pressure conditions, with natural diamond, HPHT diamond or CVD diamond substrate as the substrate, CVD diamond can be divided into CVD single crystal diamond and CVD polycrystalline diamond, CVD diamond can be grown by gas phase epitaxial method. Widely used in ultra-precision tools, semiconductors, optical materials, missiles, aerospace, lasers, electronic devices and other fields.

Cultivated diamonds are synthetic diamonds by HPHT (high temperature and high pressure) method and CVD method. Cultivated diamonds are comparable to natural diamonds in terms of crystal structure integrity, transparency, refractive index, dispersion, etc. As an emerging choice in the field of diamond consumption, they can be used to make all kinds of diamond jewelry and other fashion consumer goods.
