Synthetic diamond micro-powder is produced by crushing and shaping of synthetic single-crystal diamond grits with special techniques.The product can be classified into PDM(Premium Diamond Micro-powder) and EDM (Economical Grade Diamond Micro-powder )

PDM

Characteristics:

1. Domestic top-quality single-crystal diamond materials are used as raw materials;technical data such as static pressure strength, abrasive performance and thermal stability are higher than standards of the industry.

2. Round and smooth crystal; fewer absorbed particles on powder surface; no bar- or plate-shaped particle.

3. Extremely narrow range of granularity distribution and excellent granularity control.

4. Special processing techniques enable the content of impurities to be about 1/100000.

Usage: 

• The premium diamond micro-powder is suitable for applications in industries that have high demands on grinding and polishing, such as the precision equipment industry, as well as in sectors that are strict with impurity content, like electroplating and production of poly-crystalline diamond compacts. 

EDM

Characteristics:

1. Complete form of crystal with sharp edges; hard and crisp texture; extremely powerful grinding; good thermal stability.

2. Even granularity distribution; granularity control satisfying standards.

3. Content of impurities satisfying industrial code.

Usage: 

• The economical grade synthetic diamond micro-powder demonstrates extremely high grinding efficiency in sectors where the requirements on processing accuracy and strength are not high, such as production of diamond grinding wheel as well as polishing of stone materials.
