In materials science, a refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically composed of oxides or carbides, nitrides etc. of the …

Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1,000°F [538°C]) encountered in modern manufacturing. More heat-resistant than metals, they are used to line the hot surfaces found inside many industrial processes. In addition to being resistant to thermal stress and other physical phenomena induced ...

Meaning of Refractories: The term refractories embraces all materials used in the arts for the construction of heat resisting containers, using the word in its broadest sense, whether it be to afford space for the evolution of gases in combustion processes or the holding of molten charges or of solids undergoing heat-treatment.

Refractory materials refer to inorganic non-metallic materials with a refractoriness not less than 1580°C. They are used as structural materials for high-temperature furnaces and other thermal equipment, as well as materials for industrial high-temperature containers and parts, and can withstand corresponding physical and chemical changes.

Refractory materials generally refer to the inorganic nonmetal materials with a refractory degree of 15800C or above. Refractory materials include natural ores and various products made by certain purposes and requirements through certain processes, which have certain high-temperature mechanical properties and good volume stability. They are the necessary materials for various …
