Thermal shock resistant ceramic composites

摘要: A ceramic composite is able to whithstand temperatures in excess of 2200 F on a repeated basis without cracking due thermal shock. The has web reinforcement fibers; and matrix that substantially the after firing step. formed around by impregnating with sol containing alumina and, some cases, rare earth oxides, impregnation. may be three-dimensional orthogonal weave fibers, where fibers are transitional phase alumina. essentially free Group I II metals transition metal oxides. used as refractory brick or lining also an insulatingmaterial its chemically non-reactive nature.
