In the ceramic industry, these are the bricks used to build kilns. This term grows out of their ability to withstand high temperatures that would melt or deform structural bricks.
A brick capable of withstanding high temperatures without deforming. 'Insulating firebricks' have the additional advantage of acting as good insulators due to the large pockets of air in the matrix of the brick. There are many different kinds of firebricks available. Although they might appear similar, fire bricks are much more expensive than structural bricks and can withstand temperatures that would melt most common bricks. Firebrick types are categorized for their heat duty and the types of materials and atmospheres they must come into contact with. A wide variety of refractory shapes are also produced.
Users of firebricks look for technical specifications that include things like thermal expansion, thermal conductivity, resistance to spalling. Bricks are also classified according to chemical and material composition, method of manufacture and the application to which they will be put.
In the ceramic industry, refractory materials are those that can withstand a high temperature without deforming or melting. Refractories are used to build and furnish kilns.
In the ceramics industry, clays that are resistant to deforming and melting at high temperatures are called fireclays. Kiln bricks are often made from fireclay.
