Mullite-Zirconium Composites Reinforced with Ceramic Fibres Resistant to 1450°C; Obtaining and Properties

The purpose of this paper was to obtain some mullite-zirconium matrix composites, reinforced with ceramic fibers resistant to 1450 C. In order to establish the compositions, the raw materials were ground, depending on their nature, in various ways, and the characteristics of resulting powders were established. The authors determined evolution of the ceramic, mechanical and structural characteristics, as a function of heat treatment temperature, for various reinforcing coefficients. (Author)
