COATED PARTICLES FOR SYNTHESIZING DIAMOND AND PROCESS FOR PRODUCTION OF DIAMOND ABRASIVE FOR SAWING

摘要

It is an object of the present invention to provide a method for synthesizing high-strength diamond particles with good yields and easily. As a solution, one fine particle diamond single crystal 1 is used as a metal powder or diamond powder as a solvent for diamond synthesis. Diamond is synthesize | combined using the diamond-synthesized particle | grains coat | covered by the coating layer 2 which adds non-diamond carbon powder. Further, the aggregate of the particles for diamond synthesis or the mixture of other required powders is compressed by pseudo cold isotropic pressing to form a compact 15, and the diamond is synthesized from the compact. .
