Light Weight Silica Brick is with silica content more than 91%, the bulk density of 1.2 g / cm3. It is made of crystal silica as raw material by adding into compound flammable substance.
Light weight silica brick is mainly used to preserve heat in glass industry, iron&steel industry and ceramic furnace.The main applications are the low temperature parts such as blast furnaces and hot blast furnaces, waste incinerators and glass melting furnaces.
