top silicon cardbide refrctory is acidic or basic

Refractory - Wikipedia

30/4/2017· Basic refractories – Basic refractories are those which are attacked by acid slags but stable to alkaline slags, dusts and fumes at high temperatures. Since they do not react with alkaline slags, these refractories are of considerable importance for furnace linings where the environment is alkaline such as steelmaking operations.

Classifiion of Refractory Brick Containing Zirconium

Zirconium refractory brick. Belonging to an acidic material, the product is made from natural zircon sand (ZrSiO2). Zirconia refractory brick is different from the silica-alumina refractory brick and carbon-containing series of refractory brick, good slag resistance, thermal expansion rate is small, the thermal conductivity decreases with increasing temperature, load softening temperature, wear resistance.

silicon carbide why we use it in uzbekistan

Silicon carbide occurs naturally, although rarely, with the molecular formula SiC. One molecule of silicon carbide is one silicon atom and one carbon atom. When grains of silicon carbide are manufactured and fused together, they form an extremely hard, durable substance that is used in specialized items like car brakes, turbine mechanics, and certain types of seals and bearings.
