Ceramic Fiber

Ceramic Fiber

The ceramic fiber is manufactured from high purity raw materials alumina powder, silica sand for the high temperature grades and zircon sand is also used, The ceramic mixture is heated in an electric furnace to temperatures in excess of 2000℃ and the steam of molten material is drawn into fiber by either spinning or blowing. Ceramic fiber bulk fiber are loose, long and flexible with high refractory properties, and are produced by "blown" and "spun" processes. Ceramic fiber bulk and chopped fiber show a high temperature stability and an outstanding chemical stability (excluding hydrofluoric and phosporic acids and strong alkalis) is complemented by their resistance to oxidation and reduction. Ceramic fiber bulk and chopped fibers are available in a variety of lengths, mean diameters, and chemistries. They are used as the base for the production of blanket, moldable, and vacuum formed board and shapes.
