Application of Neutral Alumina Refractory Bricks in Kilns

by

Neutral refractories are primarily composed of mullite, corundum, or carbon (Al₂O₃, ZrO₂, CrO₃, SiC) as the main crystalline phase. At high temperatures, they exhibit good resistance to the chemical reactions of acidic slag, alkaline slag, fluxes, and other refractory materials, which can corrode other refractories. Strictly speaking, neutral refractories refer only to carbonaceous refractories, including … Read more

Application of High-Alumina Refractory Materials in Various High-Temperature Industries
