Abstract
A new hard material, the B-C-N heterodiamond, was synthesized by the shock- compression method. The heterodiamond is a polycrystalline material coagula ted with nano-crystallites and the fine powder is tinged with deep bluish b lack. The heterodiamond was confirmed to have both the highest hardness of diamond and the excellent heat resistance of cubic BN. These characteristic properties are due to the diamond structure combined with the sp(3) sigma- bonds among carbon and the hetero atoms. (C) 1999 Elsevier Science S.A. All rights reserved.
