Molybdenum (Mo) is a white platypodinae metal with a melting point of 2610 °C. In its pure form it is a hard and ductile metal of moderate hardness, high thermal conductivity, high corrosion resistance and low expansion coefficient. as the alloying additive is molybdenum promotes hardenability and increased toughness, other metals, povyshaet the limit of tensile strength and creep resistance. Alloying with molybdenum (1% or less) and considerably improve abrasion resistance, corrosion resistance and high temperature strength and toughness of the matrix material.
Since the molybdenum atom has almost the same dimensions as the atom of tungsten, it advantageously replaces tungsten in alloy steels, allowing you to achieve the same metallurgical effect at twice the density. In addition, two external e-rings are incomplete; this allows it to form chemical compounds where the metal is di-, tri-, Tetra-, Penta — or hexa-valent, this leads to a significant diversity of its catalytic properties.
The production of molybdenum
The raw material is its disulfide MoS2, which is in the process of production transforms the technical oxide of MoO3. For this purpose, multi-phase furnaces in which molybdenum concentrate are fed with a stream of heated air and gases blown from the bottom. When heated, the concentrate is heated, and under the influence of flotation reagents is converted to MoO3. This exothermic reaction is controlled by adjusting oxygen and water jets, which, if necessary, cool the oven.
Further technical oxide MoO3 is converted into briquettes, which are fed directly into the furnace for the production of alloy steels. Such briquettes are also used for the manufacture of ferromolybdenum, but if desired, more purified products from this metal, technical MoO3 need to be cleaned before chemically pure MoO3 by sublimation. This is carried out in electric retorts at temperatures from 1200 to 1250 °C. the Furnaces consist of quartz tubes wound with heating elements of molybdenum wire, which are protected from oxidation with a mixture of refractory materials — brick paste and wood charcoal.
