Abstract

Provided are inorganic fibers containing calcium and alumina as the major fiber components. Also provided are methods of preparing the inorganic fibers and of thermally insulating articles using thermal insulation comprising the inorganic fibers. The fibers are resistant to temperatures of 1100oC and greater, and are resistant to flux attack.
