China Clay refractory brick exporter

Clay refractory brick

refractory brick are made of high quality bauxite and fireclay: Al2O3 content is 38%-55%, SiO2 content is 42%-58%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1790℃, refractoriness under load is 1250-1550 ℃, line expansion coefficients is low, with good thermal shock resistance and  strong ability to resist erosion acid slag. It is widely used in industrial kilns, furnaces, boilers,etc.
