Abstract

1307713 Abrasive articles MEGADIAMOND CORP 9 April 1970 [17 April 1969] 16845/70 Heading C4V A rigid diamond compact consists of discrete diamond particles bonded together by not exceeding an equal volume of a non-diamond abrasive substance having a Knoop (100 gram.) hardness of at least 1000. The bonding abrasive may be boron carbide, silicon carbide, titanium carbide, titanium boride, aluminium boride, silicon boride, zirconium carbide, aluminium carbide, aluminium oxide, tungsten carbide, boron nitride, hafnium carbide, niobium carbide, silicon nitride, beryllium carbide, vanadium carbide, silicon, tantalum boride, vanadium boride, beryllium oxide, magnesium oxide, aluminium nitride or boron phosphide. The diamond particles may be less than 325 mesh United States Standard particle size. The materials may be made by subjecting a mixture of the diamond particles and the abrasive or a progenitor of such a substance to a temperature of at least 900‹ K. and a pressure of not less than 10 kilobars at which diamond is crystallographically stable.
