Refractory Cement with High Refractories for Furnace Lining is made out of a naturally-occurring material known as bauxite. This material includes aluminum hydroxide, which is what gives the bricks such great warmth resistance. Refractory Cement also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.
