敦煌What are the application aspects of diamond powder?

Diamond powder, as a kind of superhard abrasive, has a very superior grinding ability, and is increasingly valued by various industrial developed countries. The grinding ability of diamond micropowder includes the grinding ability of the workpiece and its own wear and crush resistance, which depends on its microhardness, particle size, strength, particle shape, and thermal and chemical stability.

In summary, the application of diamond powder as an abrasive has three major aspects:

(1) For the manufacture of resin bonding tools, metal bonding tools and electroplating tools;

(2) For grinding or polishing of various precision components in industry, science and medicine; 

(3) As a fine abrasive for mold processing, gem polishing processing, gem bearing processing and manufacturing.

In addition to the application of diamond powder as an abrasive material, another major use is to use as a functional material. For example, the use of its thermal and electrical properties. By mixing diamond powder into thermosetting resin polymer, cellulose, phenolic resin or ceramic sheet, a new material with improved thermal conductivity and reduced thermal expansion can be made. Mixing diamond powder into metal sheets, such as nickel sheets or stainless steel sheets, can be made into a new sheet material with high thermal conductivity, low thermal expansion and light weight, and can be made into high-density high-energy devices for thermal control in the electronics industry.
