Abstract

A heat-resistant and oxidation-proof material contains molybdenum silicide MoSi2 and a minor amount of SiO2 and 0.06-70 by weight of silicon oxynitride. Any Si3N4 present constitutes less than 1% by weight of the nitrogen-containing material. The SiO2 may be derived from bentonite. In an example, 1% silicon oxynitride, 94% MoSi2 of grain size less than 8m , and 5% bentonite in an aqueous slurry are mixed and extruded, sintered in hydrogen at 1200 DEG C., and then in air at 1550 DEG C.ALSO:A heat-resistant and oxidation-proof material contains molybdenum silicide MoSi2 and a minor amount of SiO2 and 0.06-70% by weight of silicon oxynitride. Any Si3N4 present constitutes less than 1% by weight of the nitrogen-containing material. The SiO2 may be derived from bentonite. In an example, 1% silicon oxynitride, 94% MoSi2 of grain size less than 8m , and 5% bentonite in an aqueous slurry are mixed and extruded, sintered in hydrogen at 1200 DEG C., and then in air at 1550 DEG C. Silicon oxynitride is made by heating a mixture of 200 g. Si powder of 75m grain and 32 g. NaOH at 1400 DEG C. in a 1 : 1 N2/Ar atmosphere. The product is then leached out in a HF/HNO3 mixture and the residue contains traces only of Si and Si3N4.
