The ceramic fiber are manufactured from high purity raw material alumina powder ,silica sand for the high temperature grades and zircon sand is also used. The ceramic mixture is heated in an high temperature electric furnace and the stream of molten material is drawn into fibers by either spinning or blowing .It is produced by advanced “blown” and “spun” processes .Ceramic fiber bulk shows a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to oxidation and reduction
Excellent thermal and chemical stability
Low thermal conductivity and heat storage
Excellent thermal shock resistance and sound –absorption capability
No bonding agent and corrosive substance
Asbestos free
