Kiln furniture for use in a non-oxidizing atmosphere

摘要

Provided is a kiln furniture for use in a non-oxidizing atmosphere, which has SiC and Si 3 N 4 and/or Si 2 N 2 O as main components, contains from 0.12 to 3.0 mass% of inorganic oxides other than an silicon oxynitride and silicon oxide. The kiln furniture for use in a non-oxidizing atmosphere according to the present invention causes neither significant deterioration in strength nor breakage even if it is used in a non-oxidizing atmosphere having an oxygen concentration of 1000 ppm or less and at the same time, has a greatly improved actual service life.
