| Description |
The sintering of powders with variable nitrogen content prepared from the carbothermal reduction and nitridation of kaolin has been studied. With increasing nitrogen uptake in the starting powder, the refractoriness and the fusion point increase. The coefficient of linear thermal expansion decreases linearly with the nitrogen content of the sintered product. The product with 80% theoretical nitrogen has good oxidation resistance. The oxidation rate is parabolic, and the product contains mullite, cristobalite, and a glass. The X-sialon phase oxidises preferentially to -sialon.
