What's the frequently used refractory material?

What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica?brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing?mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc. Special Refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation?board, etc.

Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
