A pale blue naturally occuring mineral composed of [[strontium sulfate]]. Celestite is found in sedimentary stone usually in conjunction with [[halite]] and [[dolomite|dolomitic limestone]]. Specimens have been found in England (Bristol), Italy (Sicily), Mexico (Matehuala) and the U.S.(Ohio, California). Celestite is mined as a source of strontium. It is also used in the manufature of ceramics, glass, and fireworks.

An inorganic manufactured fiber that is stable at high temperatures.  Ceramic fibers are composite materials made from mixtures of [[silica]] with inorganic oxides such as [[alumina]], [[zirconium oxide|zirconia]], thoria, [[magnesia]], hafnia, [[beryllium oxide|beryllia]], [[titanium dioxide]], potassium titanate. They are used for insulation, packing, gaskets and reinforcement.

Description

An inorganic manufactured fiber that is stable at high temperatures. Ceramic fibers are composite materials made from mixtures of Silica with inorganic oxides such as Alumina, zirconia, thoria, Magnesia, hafnia, beryllia, Titanium dioxide, potassium titanate. They are used for insulation, packing, gaskets and reinforcement.

See Aluminum silicate fiber.
