Phosphate-bonded high alumina brick is preferred in several aluminum furnace linings as the phosphate causes the brick to be immune to wetting and penetration by molten aluminum. Phosphate-bonding also increases the refractory Attributes by expanding density, decreasing porosity, raising energy, and abrasion resistance.
