ABSTRACT:
h-BN-group ceramics having excellent dissolving-loss proofness against hot melt of metal, glass and the like. If 50% or more of h-BN and 1-less than 50% of complex compound consisting of two or more kinds of compounds selected from the group of (AlN, Si.sub.3 N.sub.4, Al.sub.2 O.sub.3 and SiO.sub.2) are contained in a sintered body, then dissolving-loss proofness against hot melt is remarkably improved. Furthermore, besides the aforementioned complex compound, if less than 30% of one kind or two or more kinds compounds selected from the group (AlN, Si.sub.3 N.sub.4, Al.sub.2 O.sub.3 and SiO.sub.2) is contained, then in addition to the dissolving-loss proofness, unwettability and thermal shock proofness are extremely improved.
