It can make CAF self distributed between the periclase grains gradually gather to the angle gap between the periclase grains(220 grit aluminum oxide), which can improve the high temperature strength of the brick. The CaO / SiO2 of high calcium magnesite, high silicon magnesite and dolomite containing CaO < 6% and SiO2 < 2% were adjusted to 2 ~ 3(220 grit aluminum oxide blast media). The carbon atom in this state is actually the smallest unit of diamond structure.

Static high pressure is produced in the container, so the increase of pressure is limited by the strength of the container material(80 grit aluminum oxide). The common use of bolt fastening grinding wheel is a prominent feature of the development of surface grinding technology. To reduce the formation of CAF and Fe spinel minerals with low melting point(aluminum oxide blast media 60 grit). As a kind of catalyst, metal or alloy can promote the transformation from graphite to diamond and accelerate the reaction process.

A large number of practical results show that different varieties of graphite from different places of origin have obvious influence on the yield and quality of synthetic diamond, including technological conditions(aluminium oxide sandblasting). Different metal catalysts have great influence on diamond synthesis. Obviously, not all metal elements can act as catalysts(fused aluminium oxide). This shows that the synthetic raw materials (carbon, catalyst) of synthetic diamond should be properly selected and treated.

It shall be able to meet the following requirements(fused alumina): it has the hydrostatic characteristics of transferring pressure, that is to say, the pressure formed by this solid pressure medium is the same, and the pressure in all positions and directions is the same. However, it is impossible for the solid pressure transmission medium in the actual production process to cause complete liquid static pressure. Chemically inert(150 grit aluminum oxide). Thermal stability.

In China, with the increase of calcination temperature, the compressibility should be as low as possible(white fused alumina). The composite process was adopted, and the mixture, grinding, pelletizing and calcining (in rotary density) were carried out. Generally, the higher the static state of the liquid caused by the solid pressure medium is, the more ideal the pressure medium is. The thermal conductivity should be as low as possible(60 grit aluminum oxide). Insulation shall be as high as possible.

In order to overcome this disadvantage, the stability of pressure transfer can be improved by crushing and mixing the natural wax blocks and then re pressing them(silicon carbide price). Experiments show that pyrophyllite, talc and other materials have the advantages of good sealing performance(100 grit aluminum oxide blast media). The disadvantage is the poor pressure transfer ability, which causes a considerable pressure gradient in the high-pressure cavity of diamond growth.

The melting point should be as high as possible, and the melting point should increase with the increase of pressure(arc fused alumina). In the actual production process, it is almost impossible to find a solid pressure medium that can completely and simultaneously meet all the above requirements(fused aluminum oxide). In recent decades, pyrophyllite is the most widely used solid pressure medium in the research and production of high pressure and high temperature synthesis diamond.
