As a kind of super hard abrasive, diamond powder has an extremely superior grinding ability, which has been paid more and more attention by industrial developed countries. The grinding ability of diamond powder includes the grinding ability of workpiece and its own abrasion resistance and crushing resistance, which depends on its microhardness, particle size, strength, particle shape, thermal stability and chemical stability. fgfwefwefcs

Generally speaking, the application of diamond powder as an abrasive has three aspects:

(1) used for manufacturing resin bonding tools, metal bonding tools and electroplating tools;

(2) used for fine grinding or polishing of various industrial, scientific and medical precision components;

(3) as fine abrasive, it is used for mold processing, baoyu polishing processing and gem bearing processing and manufacturing.

Besides being used as abrasive material, diamond powder is also used as functional material. Such as the use of its thermal and electrical properties and so on. A new material with higher thermal conductivity and lower thermal expansibility can be prepared by mixing diamond powder into thermosetting resin polymer, cellulose, phenolic resin or ceramic sheet. Mixing diamond powder into metal sheet, such as nickel sheet or stainless steel sheet, can be made into a new type of sheet material with high thermal conductivity, low thermal expansion and light weight, which can be made into high-density high-energy devices for thermal control in the electronic industry.

In terms of the form of diamond used as abrasive material, according to the figures published by relevant data, more than 60% of the diamond powder consumed in industry all over the world is used to make diamond gypsum,  mixture of diamond powder and grinding fluid of diamond powder.
