Fire bricks, also known as refractory bricks, are specially designed bricks capable of withstanding extremely high temperatures without melting, cracking, or degrading. They are commonly used to line fireplaces, kilns, furnaces, and wood-fired ovens.
Made from refractory ceramic materials such as alumina and silica, fire bricks are engineered to retain heat while providing structural integrity under thermal stress. They have a low thermal conductivity, which helps to improve energy efficiency in high-temperature environments.
