Chemically synthesized mullite precursor powders which are suitable materials for the production of continuous fiber-reinforced mullite composites, owing to their high sintering activity at relatively low processing temperatures were used as a matrix material. Since commercially available polycrystalline mullite fibers become instable at high temperatures, optimized slip-casting and sintering conditions were used which allowed hot-pressing of the composites at temperatures lower than 1250{degrees}C. A strong interfacial bonding between fiber and matrix has been observed due to the preferential grain growth which starts on the fiber surfaces and extends into the matrix.
