Rare earth and refractory metals

Relevance

Rare earth or rare metals — is a reference element group, the advantages of which were appreciated only in the second half of the twentieth century. First of all it is connected with the development of technology chemical and metallurgical industries. The situation is similar to refractory metals, the main applications of which is represented by space, aircraft industry I. the nuclear industry. Today Russia is among the indisputable leaders in the extraction and production of most refractory materials such as tungsten, molybdenum, vanadium, cobalt. Supplier «Auramo» offers to buy high quality products corresponding to GOST and international standards.

Application

High — temperature elements- tungsten, molybdenum, vanadium, cobalt is used as a component of solid heat-resistant alloys. Germanium is used in electronic vacuum appliances. A number of modern industries depend on structural materials based on rare earth elements. Instrument-making, machine-building, metallurgy, chemical and nuclear industry, do not have equivalent alternatives to products based on titanium, cobalt, molybdenum, tantalum, vanadium.

Tungsten

The name of the metal is translated from German as wolf foam. Tungsten — element of the sixth group of the periodic table of Mendeleev. Atomic number — 74 atomic weight — 183.9, density at room temperature = 19.3 g/cm3. Refractoriness is 3395 + 15 degrees. Tungsten is the basis of high-temperature alloys, as well as the hardest steels (high speed tool). The processing (forging, rolling, drawing) is only possible when heated. The disadvantages of tungsten include very high density, brittleness at low temperatures, low resistance to oxidation at low temperatures. Heavy tungsten is used for the trim of artillery shells, bullets and high-speed (up to 180 thousand rpm) of the rotors of the gyroscopes that stabilize the flight of a ballistic missile.

Molybdenum

The refractory metal molybdenum on properties similar to tungsten. Molybdenum has a melting point in excess of 2600 °C, a boiling point of more than 4,600 °C, Brinell hardness number — 125НВ. Molybdenum imparts resistance to heat, hardness, durability of the elite of tool steels. Today molybdenum is literally essential for parts of vacuum devices, aviation engines.

Vanadium

Vanadium is a coarse-grained material silver color. Its industrial use began not so long ago. The fact that vanadium is scattered in various rocks and minerals, and its production and processing require the use of modern technologies. Today, the alloys with vanadium has found its application in the production of steel, besides the metal is added to titanium to improve the characteristics of the latter. Also the vanadium acts as a catalyst in the production of sulfuric acid. In addition, the achievements of modern science allow the use of vanadium in medicine, textile, glass and paint industries.
