Refractory materials are a class of inorganic non-metallic materials with a refractoriness (also known as melting point) of not less than 1580℃. Refractoriness is a technical indicator that comprehensively considers the material's chemical composition, dispersion, proportion of liquid phase, and viscosity. However, defining refractory materials solely based on refractoriness is not comprehensive enough, as 1580℃ is not absolute. The current concept is defined as materials whose physical and chemical properties are permissible for use in high-temperature environments.
Literally, refractory materials are materials that can withstand high temperatures. For steel mills, low-end refractory materials include castables and fireclay, while high-end materials include those used in steel ladles Permeable bricks and electric furnace covers for electric furnaces. Refractory materials are widely used in various fields such as steel, non-ferrous metals, glass, boilers, power, military, ceramics, petrochemicals, machinery, and light industry. They are essential materials for the production, operation, and technological research and development of these fields, playing an irreplaceable role in high-temperature production.

From a professional perspective, refractory materials are inorganic non-metallic materials with a refractoriness (also known as melting point) of not less than 1580℃. Refractoriness is a technical indicator that incorporates the material's chemical composition, dispersion, the proportion and viscosity of the liquid phase, etc. However, defining refractory materials solely by refractoriness is not comprehensive; 1580℃ is not absolute. The current concept defines refractory materials as any material whose physical and chemical properties are permissible when used in high-temperature environments.
There are many ways to classify refractory materials, including by refractoriness, product shape and size, manufacturing method, and chemical properties of the components.

Classified by refractoriness: ordinary, high-grade, and special refractory materials; by product shape and size: standard, irregular, special, and special products; by manufacturing method: fired, unfired, and monolithic refractory materials; by chemical properties of the components: acidic, neutral, and alkaline refractory materials; by chemical mineral composition (more practical): aluminous, corundum, magnesia, magnesia-calcium, alumina-magnesia, and silica; monolithic refractory materials (by usage): castables, sprayables, and ramming materials.
