Refractory materials are used in linings for furnaces, kilns, incinerators and reactors.
General refractory brick material is aluminosilicate clay, thus, when rotary kiln working, the main compounds are silica&alumina inner the kiln. Certainly, siliceous bricks can bear rotary kiln highest temperature parts. However, in order to avoid chemical erosion, you need a special refractory brick to calcine dolomite, magnesite, chromite and so on.
