Refractory

heat-resistant material
Refractory bricks in United States

A refractory is a material that can stand high temperature. It is used in furnaces, kilns, incinerators and reactors. Materials to make refractory must be chemically and physically stable at high temperature, such as alumina, silica, magnesia and lime.
