Sintered corundum mullite brick

Product Name:Sintered corundum mullite brick
National sales hotline:139-0382-5488

Product introduction

     Corundum mullite brick is a high alumina refractory product composed of corundum and mullite. Corundum mullite brick refers to refractory products made of high-purity or purer raw materials. The existence of oxide impurity with low melting point will reduce its high temperature performance. The raw material of mullite, especially the content of alkali metal oxide, which is synthesized from industrial alumina powder and pure clay, bauxite or silica, should be as low as possible. The products with mullite as aggregate have good thermal shock resistance, but less erosion resistance. The products with corundum sand as aggregate have good corrosion resistance, but less thermal shock resistance.
