Abstract
A process for producing a diamond composite comprising diamond powder parles bonded together by polycrystalline diamond by (1) pressing an intimate mixture of fine opaque nondiamond carbon powder and transparent diamond powder to form a green body that is confined in either a thin walled transparent quartz vessel or a polycrystalline diamond coating; (2) using a pulse laser to quickly melt the opaque nondiamond carbon powder, and (3) allowing the carbon melt to cool and grow homoepitaxially from the surfaces of the diamond particles producing a polycrystalline diamond that bonds the diamond particles together.
