Provided are inorganic fibers containing calcium and alumina as the major fiber components. According to certain embodiments, the inorganic fibers containing calcia and alumina are provided with a coating of a phosphorous containing compound on at least a portion of the fiber surfaces. Also provided are methods of preparing the coated and non-coated inorganic fibers and of thermally insulating articles using thermal insulation comprising the inorganic fibers.

Inorganic fiber

A high temperature resistant vitreous inorganic fiber having a use temperature of up to at least 1000&#xb0; C., or greater, having after service mechanical integrity, is non-durable (soluble) in physiological fluids, and is produced from a melt containing silica, magnesia, calcia, a lanthanide series element-containing compound, and optionally zirconia.
