Selecting high quality graphite as raw material, several hours or days' machine press, the high qualiy raw monocrystalline diamond powder come out, then through crushing, shaping, purifying and grading, we get good shape diamond powder with all grits. As a kind of super hard abrasive material, it has features of high hardness, strength, toughness, good thermal conductivity and fine heat stability and impact resistance.
