Main zvinhu zve acidic, kwazvakarerekera uye alkaline lining zvinhu

Acid lining material: tetravalent compound SiO2, ZrO2, nezvimwewo, siliceous, semi-silica, ivhu, zirconium, semi-zirconium

Neutral lining materials: trivalent compounds Al2O3, Cr2O3 uye yakasimba covalent bond crystalline minerals C, SiC, high aluminium, corundum, chromium, carbon, silicon carbide, silicon nitride, nezvimwewo.

Alkaline choto lining zvinhu: divalent makomisheni CaO, MgO, nezvimwewo, magnesia, dolomite, magnesia aluminium, magnesia chromium.
