Abstract

The invention provides a novel highly refractory sintered body based on a tal diboride such as TiB.sub.2 or Mo.sub.2 B.sub.5 and W.sub.2 B.sub.5 containing a binder ingredient. The high-temperature performance of the sintered body is further improved by including an auxiliary additive ingredient selected from several carbides, nitrides, silicides and oxides such as WC, TiC, TaN, TiN, MoSi.sub.2, TiO.sub.2, Al.sub.2 O.sub.3, B.sub.2 O.sub.3 and the like in a limited amount.
