WebMétal réfractaire. Les métaux réfractaires sont une classe de métaux qui sont extrêmement résistants à la chaleur et à l' usure. L'expression est surtout utilisée dans le contexte de la … In metallurgy, refraction is a property of metals that indicates their ability to withstand heat. Metals with a high degree of refraction are referred to as refractory. These metals derive their high melting points from their strong intermolecular forces. Large quantities of energy are required to overcome intermolecular forces. Some refractory metals include molybdenum, niobium, tungsten, and tantalum. These materials ar…
