The refractory metals are metals which possess excellent resistance towards heat and water when used in material science, engineering and metallurgy. Examples of such metals include molybdenum, niobium, and rhenium among others. Refractory metals are extracted from ore concentrates and are further processed into chemicals and powders. These metals possess extremely high melting point. Refractory metals are used in the construction of furnaces, filaments, nuclear reactor control rods, and other similar applications that involve exposure to extreme temperatures.
