Refractory shapes include precast cement and fused or sintered refractory products that are formed prior to installation in furnaces, boilers or other high temperature equipment. Refractories are hard, heat resistant materials and products such as alumina, silicon carbide, fire clay, bricks, precast shapes, cement or monolithics and ceramic kiln furniture. Ceramics and refractories have high melting points are suitable for applications requiring wear resistance, high temperature strength, electrical or thermal insulation or other specialized characteristics.

Refractory bricks, blocks, and tiles are stacked to form insulating furnaces, boilers or other thermal process vessel walls. The bricks are usually cemented together with refractory mortar.
