Description

A manufactured fiber made from aluminum silicate. Aluminum silicate fibers are capable of withstanding temperatures up to 1200 C. They can be made by several processes. Short whiskers (about 1 cm) are made by heating aluminum fluoride with silica at 1000-1200 C. Longer fibers are made from melted aluminum oxide-silica mixed with small amounts of boron or zirconia. Aluminum silicate fibers are sometimes referred to as ceramic fibers and high temperature fibers. They are made into nonwoven mats ranging in thicknesses from paper-like to blanket-like. Aluminum silicate fibers are used for insulation, packing, smoke stack filters, gaskets, plastic reinforcement, and fireproof panels.
