Zusammenfassung:1325204 Sintered boron carbide UNITED STATES BORAX & CHEMICAL CORP 23 Sept 1971 [7 Oct 1970 (3)] 47744/70 47745/70 and 47746/70 Heading C7D Sintered B-C compounds e.g. B 4 C are made by sintering at 1900-2300‹C. cold pressed compacts containing the B-C compound and 3-15 per cent weight of at least one of Si, Al, Mg or a metal boride may be added by mixing with the powdered B-C prior to compaction or by impregnation of the pressed compact with the melt or vapour of the additive. The boride may be of Cr or Ti and compaction is at 15-30 t.s.i.
