What are the raw materials for отко чыдамдуу кирпичтер?

There are many kinds of raw materials for making refractory bricks. From a chemical point of view, all elements and compounds with a high melting point can be used as raw materials; from a mineralogical point of view, all high-refractory minerals can also be used as raw materials for refractory bricks. What are the raw materials of refractory bricks, generally divided into: soil, stone, sand, silty and others.

(1) Soil quality: kaolin, clay and diatomite

(2) Stone quality: bauxite, fluorite, kyanite, andalusite, sillimanite, forsterite, vermiculite, mullite, chlorite, dolomite, magnesia alumina spinel and silica, Cordierite, corundum, coke gemstone, zircon

(3) Sand quality: quartz sand, magnesia sand, chrome ore, etc.

(4) Powder quality: aluminum powder, silicon powder, silicon powder
