Ceramic fibre is made from well chosen aluminum ore which go through high temperature melting in molybdenum wire furnace, vertical spinneret, selection by wind to remove shot, organic coupling and high speed cutting .
It has features of good toughness, high temperature resistance, high strength, easy dispersion ，low shot and stable quality.
