Manufacturing capabilities

Gemcolite®-Alumina can be formed as boards, sleeves, combustion chambers and any custom shape. In addition, Refractory Specialties has a wide range of machining capabilities for added details and tight tolerances. Insulation Boards may be surface treated to provide additional erosion or chemical resistance for use in hostile environments. Gemcolite®-Alumina materials can have hardware molded or installed into them to provide easy installation.

Excellent Energy Conservation

Low thermal conductivity and heat storage make Gemcolite®-Alumina materials an outstanding energy saver. Thermal shock resistance permits fast cycling without cracking or spalling.
