In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]

The meaning of REFRACTORY is resisting control or authority : stubborn, unmanageable. How to use refractory in a sentence.

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

Refractory, any material that has an unusually high melting point and that maintains its structural properties at very high temperatures. Composed principally of ceramics, refractories are employed in great quantities in the metallurgical, glassmaking, and ceramics industries, where they are formed

REFRACTORY definition: 1. not affected by a treatment, change, or process: 2. difficult to control; unwilling to obey…. Learn more.

Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. The expression is mostly used in the context of materials science, metallurgy and engineering. The definition of which elements belong to this group differs.

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.

1. hard or impossible to manage; stubbornly disobedient: a refractory child. 2. resisting ordinary methods of treatment. 3. difficult to fuse, reduce, or work, as an ore or metal. n. 4. a material that retains its shape and composition even when heated to extreme temperatures. 5. refractories, bricks of various shapes used in lining furnaces.

Feb 11, 2023 · Lining materials in thermal equipment, materials for high-temperature vessels, and parts in high-temperature devices are refractories. Generally, the refractoriness of refractories is above 1580 °C. Refractories emerged with high-temperature technology.

Refractory materials are specialized inorganic substances capable of withstanding high temperatures and corrosive environments without losing their structural integrity. Typically, these materials can endure temperatures surpassing 1000 degrees Fahrenheit (538 degrees Celsius) and are essential in various industrial applications, particularly in furnaces and storage vessels …
