Refractory Fire Brick is refractory ceramic materials widely used in fireplaces, kilns, fireboxes, lining furnaces, etc. It is made for withstanding high heat and temperature. In addition to this, it comes with low thermal conductivity features to make sure to save high on energy. Refractory Fire Brick can be used in various applications, where high mechanical or thermal stresses are required like wood-fired kiln. With 40% alumina content, the service temperature of this Refractory Fire Brick can be easily increased.
