Ceramic fiber bulk is manufactured through blow or spun production techniques,high quality raw materials such as flint clay ,alumina ,silica sand have ensured the outstanding thermal refractory and insulation ,flexibility in application refractory linings and insulation tools ,it has also been made into felt ,blanket ,board and paper etc via our technical expertise.At present ,the chopped ,lubricated and milled bulk are available. The solution is heated and inspissated into fiber under specific conditions and got polycrystalalumina fiber after the heat treatment. Ceramic fiber bulk show a high temperature stability.Low weight , heat capacity and an outstanding sound absorption is complemented by their resistance to shock and erosion.
