Light corundum mullite bricks
prepared by sintering of high temperature after molding taking white corundum,fused mullite
Light corundum mullite bricks are prepared by sintering of high temperature after molding taking white corundum,fused mullite and abletive agent mixedin definite proportion as raw material. The products have the advantages of high temperature resistance,low thermal conductivity(good insulating efficiency,thin kiln wall and low cost),high strength,and high thermal shock stability. They are widely usedin various inner linings and heat insulation layers of high temperature kilns.
