Phosphate-bonded high alumina brick is favored in many 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 Houses by raising density, reducing porosity, escalating strength, and abrasion resistance. High alumina brick refractories can have two https://emilianovgpyh.wikissl.com/2062558/ceramic_heat_bricks_an_overview
