PROBLEM TO BE SOLVED: To provide the ceramic having excellent thermal shock resistance, heat insulation, low thermal expansibility, etc., and in addition excellent mechanical properties such as strength and toughness. SOLUTION: This fiber-reinforced ceramic has a density of >=90% based on a theoretical density, and is obtained by reinforcing a base material consisting mainly of a crystal composite tissue comprising calcium silicate and lithium aluminosilicate with one or more kinds of fibers selected from inorganic fibers and metal fibers. This method for producing the fiber-reinforced ceramic comprises molding a raw material composition containing one or more kinds of fibers selected from inorganic fibers and metal fibers, calcium silicate and lithium aluminosilicate and subsequently sintering the molded product at 900-1,400 deg.C. |
