Abstract

A mixture which exclusively consists of 98% by weight of nitrogen silicide, 1 to 60% by weight of aluminium nitride, 0.5 to 50% by weight of silica and 0.05 to 60% by weight of alumina or of 40-60% by weight of aluminium nitride, 15 to 45% by weight of silica and 0.05 to 50% by weight of alumina, is sintered at a temperature from 1200 DEG C to 2000 DEG C. Alternatively, the mixture contains at least 95% of the first-mentioned 4 substances and glass, melted at the said temperature, in the form of a borosilicate glass, iron silicate glass, manganese glass or lithium glass. This silica is present in a molar ratio of 1:2 with a part of the aluminium nitride, and the alumina is present in a molar ratio of 1:1 with the remainder of the aluminium nitride. In the absence of nitrogen silicide, the silicon/aluminium/nitrogen/oxygen atomic ratio is 6-z:z:8-z:z, with z > 4 and </= 5. The constituents of the mixture react with one another to form a ceramic material. This is intended for materials exposed to high temperatures.
