摘要： Silicon-carbide-whisker-reinforced cordierite ceramic products are prepared by uniformly incorporating the whiskers in the ceramic batch, forming the batch into a product preform, e.g. by extrusion, and firing the preform according to a process wherein the conversion of the oxide batch materials to cordierite occurs under a non-oxidizing atmosphere. Significant improvements in product strength and thermal downshock resistance are obtained.

摘要： A silicon carbide fiber reinforced barium modified magnesium aluminosilicate matrix composite is described having high strength and thermal stability at temperatures in excess of 1200.degree. C. The matrix material contains about 5% to about 14% magnesium oxide and about 5% to about 25% barium oxide.

摘要： A silicon carbide fiber reinforced glass-ceramic matrix composite is disclosed having high strength, fracture toughness, and improved oxidative stability even at high temperature use, e.g., in excess of 1000.degree. C. The composite is made up of a plurality of glass-ceramic layers, each layer reinforced with a plurality of unidirectional continuous length silicon carbide or discontinuous SiC fibers. The composite is formed by starting with the matrix material (preferably lithium aluminosilicate) in the glassy state and converting it from the glassy state to the crystalline state after densification of the composite. Ta or Nb compounds are added to the matrix composition prior to consolidation to form a reaction or diffusion barrier around the SiC fiber, resulting in composites with high temperature oxidation stability. Substitution of at least part of the Li.sub.2 O in the matrix with MgO results in an even higher temperature stable composite, e.g., up to about 1200.degree. C.
