The refractory material is one that retains its strength at high temperatures, which must be chemically and physically stable at high temperatures. Depending up on the operating environment, they have to be resistant to thermal shock, chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion. The most common materials used in the manufacturing of refractories (fired and monolithic) are Aluminium oxides and Silicon Carbide. Other materials are zirconia, magnesium, fused spinal, fused mullite, bubble alumina etc.
Refractory materials are used in linings for furnaces, kilns, incinerators and reactors. They are also used to make crucibles etc. Our wide range of grit sizes in precise, uniform compositions and with desired mechanical strength, chemical stability, thermal conductivity, abrasion and corrosion resistance to meet your application challenges.
