Refractories

Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they must be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion. Refractories must be chosen according to the conditions they face.

Brown fused alumina, white fused alumina, silicon carbide and magnesia are the most important materials used in the manufacturing of refractories. Some applications require special refractory materials. Zirconia alumina is used when the material must withstand extremely high temperatures.

DOMILL offers refractory materials are used in furnaces, kilns, incinerators, and foundry industries. Especially, A68 brown fused alumina has a high alumina and low iron content with low magnetic properties. It is processed in an electric arc furnace, giving it excellent hardness, strength and durability. Its thermal properties make it an excellent choice for many refractory applications.
