ABSTRACT:
A composition for forming a high temperature, acid and alkali resistant refractory fiber. The compositional formulation, by weight, is 56-76% silica, 12-33% alumina, and 3-22% zirconia. These fibers are chemically resistant in both acidic and alkaline environments even when heat treated to temperatures exceeding 500.degree. F. (260.degree. C.) in such environments.
