Abstract
A sintered polycrystalline diamond material (PCD) of extremely fine grain size is manufactured by sintering under high pressure/high temperature (HP/HT) processing, a diamond powder which is blended with a pre-milled source catalyst metal compound. The PCD material has an average sintered diamond grain structure of less than about 1.0 μm.
