Why can Fire Clay Bricks be Used as Refractory Materials?

Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. Fireclay refractory bricks are manufactured from unfired refractory bond clay and fireclays (chamotte), fired refractory clay or similar grog materials . Fireclay refractory bricks have two main components namely 18 % to 44 % of alumina (Al2O3) and  50 % to 80 % of silica (SiO2).

Fire clay bricks is resistant to high temperatures, having fusion points higher than 1,600 °C (2,910 °F); therefore it is suitable for lining furnaces, as fire brick, and for manufacture of utensils used in the metalworking industries, such as crucibles, saggars, retorts and glassware. Because of its stability during firing in the kiln, it can be used to make complex items of pottery such as pipes and sanitary ware.

Fire clay-brick fire bricks consisting of 30-45% Alumina, a hard fired "Super duty" Fire clay-brick.

Fire clay-brick mainly used for high alumina (High-Alumina) bricks for steel/iron making furnace, glass kiln, ceramic tunnel kiln, cement kiln etc.

Fire clay-brick with excellent insulating properties and high hot strengths at up to 1800°C.

Fire clay-brick also with these features, acid resistant, chemically resistant and thermally durable, etc.

Fire clay bricks for sale are a kind of aluminum silicate refractory material. Fire clay bricks are made from clay minerals. Fire clay bricks have low porosity and are durable for various re-heating process. They are mainly used in the low temperature parts of blast furnaces, waste incinerators and glass melting furnaces. Fire clay bricks are the most widely used refractory bricks with a long history. If you want to buy high quality and cheap fire clay bricks, welcome send e - mail to ask for the free price list!
