摘要：

It has been found by X-ray diffraction and structure analyses that in the reaction sintering of cubic boron nitride composites from the cBN+8 % Al+26 % TiC mixture at high pressure and temperature (4.2 GPa, 1750 K) in the binding ceramics composition in addition to AlN, there forms a Ti (x) Al1-x B-2y N2(1-y) solid solution, in which titanium and aluminum atoms generate a skeleton, whose composition is close to the equimolar one and boron and nitrogen atoms are distributed randomly in graphite-like networks.
