Refractory metals

Melt metal refers to metals and alloys with tungsten, molybdenum, tantalum, niobium, and other unique properties (high melting points, many valuable electrical characteristics, high temperature mechanical properties, etc.), widely used in electric light sources, electronics, information, electricity, metallurgy, chemical, aviation, aerospace and other departments, become the basic materials of national economy, indispensable materials of national defense construction, high technology key materials and important materials closely related to people's quality of life.

Chemical

The refractory metals have a good sort of chemical properties because they're members of three distinct groups in the periodic table. They're easily oxidized, but this reaction is bogged down within the bulk metal by the formation of stable oxide layers on the surface. The oxide of rhenium is especially more volatile than the metal, and thus at heat the stabilization against the attack of oxygen is lost, that’s because the oxide layer evaporates. All of them are relatively stable against acids.

Applications

Refractory metals are utilized as catalysts in lighting, tools, lubricants, natural process control rods for their chemical or electrical properties. Due to their high freezing point, refractory metal components are never fabricated by casting. The method of metallurgy is employed. Powders of the pure metal are compacted, heated using current, and further fabricated by cold working with annealing steps. Refractory metals are often made into wire, ingots, rebars, sheets or foil.
