Refractory Bricks
Refractory bricks are bricks specifically designed to withstand high temperatures and prevent damage from high temperatures.
They are usually made of refractory ceramic materials, such as alumina, silica, and magnesium oxide. Refractory bricks come in various shapes and sizes to meet the specific needs of different applications.
Application
It is usually used to arrange and protect fireplaces, furnaces, kilns, and other heating applications. Refractory bricks are made of special materials that can withstand thermal shock, wear resistance, and maintain their structural integrity even under extreme conditions.
