ABSTRACT:
A high temperature, high strength in-situ reinforced ceramic composite adapted for use in various applications including missile radomes in which microwave transparency is required in a high temperature environment. The material is manufactured by a pressureless sintering process, in which silicon nitride and barium aluminosilicate are blended together, isostatically pressed into a desired shape and thereafter sintered.
