Refractory
What is refractory fire brick?
Refractory bricks are designed to withstand high temperatures without melting or breaking down.
They are used in industries where conventional construction materials would not survive, such as in furnaces, kilns, and incinerators. Refractory bricks are resistant to thermal shock, erosion, and chemical attack. They are made from refractory materials like clay, alumina, silica, and magnesia, which are heated to create a hard and durable material. And their specific composition depends on the intended application and temperature range.
