Molybdenum is a refractory metal, t (melting) - 2616 ° С. Molybdenum is characterized by a high melting point coupled with a low vapor pressure, high modulus of elasticity and high thermal stability. It is characterized by high corrosion resistance in melts and vapors of alkali metals. Molybdenum is slightly inferior to tungsten in mechanical strength, but it is easier to process by pressure. In addition, due to the lower density (in comparison with tungsten), molybdenum-based alloys have a higher specific strength (at temperatures below 1370 ° C). At the same time, the price of molybdenum is slightly lower than that of tungsten. Due to its properties and qualities, molybdenum is one of the main industrial metals and is widely used in the electro - vacuum and radio - electronic industries, in special machine and instrument engineering, aircraft and rocket engineering.Molybdenum is often used as an alloying additive to a variety of alloys to give the latter improved strength characteristics.
Molybdenum brands
The most common brands of molybdenum are:
МЧ – Pure molybdenum without impurities
МЧВП – Pure molybdenum without impurities, produced by vacuum melting
МРН – Molybdenum for general purposes, does not contain supplements, but contains a greater amount of impurities than in the brands of pure molybdenum and pure molybdenum produced by vacuum melting
МК – Contains silica-alkali additive
ЦМ – Contains a zirconium or titanium additive
МР – An alloy of molybdenum with rhenium
МВ – An alloy of molybdenum with tungsten
NPO GKMP LLC supplies to order according to customer drawings a wide range of molybdenum products: crucibles, boats, rods, hairpins, rings, molybdenum heaters, etc.
The refractoriness and heat resistance of molybdenum (melting point 2620 ° C) determines the further properties of the product, so molybdenum crucibles have proven themselves under vacuum and inert gases. In addition, due to their resistance to electrochemical corrosion and oxidation at high temperatures, their use in aggressive environments is possible.
Molybdenum crucibles are widely used in metallurgy, foundry and chemical industries, in the field of metalworking and mechanical engineering in the field of sintering and annealing of raw materials, smelting, single crystal growing and metal evaporation under specified conditions.
Crucibles are made by casting or molding. The crucible is molded in the following ways: sintering, furring, spin molding. Due to the fact that the crucible should not interact with the materials placed in it, only high-purity molybdenum is used in the production.
Depending on the purpose, the molybdenum crucibles have the most diverse shapes and sizes: cone, ellipse, with a rounded edge, without a bottom, a boat, micro and industrial crucibles, wide crucibles, tall crucibles with a reinforced edge, etc.
Technical data of Molybdenum Crucibles
The final price of the molybdenum crucible is determined by the complexity of the product and the crucible manufacturing method itself.
NPO GKMP LLC supplies made-to-order molybdenum crucibles, including bowls and boats of various shapes and sizes according to drawings.
Molybdenum screens have high heat resistance and mechanical strength, are used as accessories for high-temperature furnaces with a vacuum or hydrogen atmosphere, and due to its high corrosion resistance it can be used in aggressive environments.
NPO GKMP LLC offers molybdenum screens of various sizes, designs and difficulty levels according to individual drawings
