Refractories are produced from natural and synthetic ingredients, usually not metals, or a combination of compounds and minerals such as alumina, fireclays, bauxite, chromite, dolomite, magnesite, silicon carbide, and zirconia.
Very high temperature resistant refractory materials of 3000 ° C or more without degradation or softening. Fireproof materials include ceramics and certain superalloys, from simple ones such as fireplace brick layers, furnace heat insulation, to sophisticated ones such as heat protect jet engines and rockets and for space shuttles.
Refractories are used to collect heat and protect processing equipment from intense temperatures. In industry, they are used to coat boilers and furnaces of all types (reactors, ladles, stills, kilns, etc.).
