Molybdenum alloys

Molybdenum matrix by adding other elements consisting of non-ferrous alloys. Major alloying elements are titanium, zirconium, hafnium, tungsten, and rare earth elements. Titanium, zirconium, hafnium, molybdenum alloy element not only for the solid solution strengthening effect, maintain low temperature ductility of the alloy, but also form a stable carbide dispersed phase, improve tensile strength and recrystallization temperature. Molybdenum metal alloys have good thermal conductivity and low coefficient of expansion, at a high temperature (1100 ~ 1650 ℃) high strength, easy processing than tungsten. Can be used as the gate and the anode tube, electric light source support material, as well as parts and components for the production of die-casting and extrusion dies, spacecraft.

Molybdenum alloy is widely used in other areas

molybdenum metals alloy used in other fields and chemical industries also expanded. For example, molybdenum disulfide lubricants are widely used in various types of machinery lubrication, molybdenum and gradually used in nuclear power, new energy and other fields. Because of the importance of molybdenum, governments view them as strategic metals molybdenum in the early twentieth century was a large number of weapons and equipment used in manufacturing, modern high, fine, sharp equipment higher material requirements, such as molybdenum and tungsten, chromium, vanadium alloys for the manufacture of ships, rockets, satellites of the alloy components and spare parts. Molybdenum coated in thin-film solar and other industries, as the substrate surface of different films is also widely used.

Application of pure molybdenum

Pure molybdenum wire for high-temperature furnace and EDM wire cutting as well; molybdenum sheet used to make radio equipment and X-ray equipment; molybdenum high-temperature ablation, mainly for Cannon Barrel, manufacturing rockets vents, tungsten bulb holder . Canada molybdenum alloy steel can improve the elastic limit, corrosion resistance and maintain a permanent magnetism, molybdenum is seven micronutrients in a plant growth and development needs, without it, plants can not survive. Animals and fish and plants, also need molybdenum.

Molybdenum metals and their compounds

Molybdenum metals is widely used in tubes, transistors, and rectifiers and other electronic devices. Molybdate molybdenum oxide and chemical and petroleum industries in the fine catalyst. Molybdenum disulfide is an important lubricant for the aerospace and machinery industries. In addition, molybdenum disulfide because of its unique nature of resistance to sulfur, can under certain conditions, catalytic hydrogenation of carbon monoxide to take alcohols are C1 chemical catalysts promising. molybdenum is a trace element necessary for the plant, trace element fertilizers used in agriculture.

What is the use of molybdenum?

Molybdenum is mainly used in the steel industry, most of which is used directly in the post-industrial molybdenum oxide briquette steel or cast iron, molybdenum iron smelting small part and then used in steelmaking. Low alloy steel molybdenum content of not more than 1%, but this aspect of consumption accounts for about 50% of the total consumption of molybdenum. Stainless steel, molybdenum is added, can improve the corrosion resistance of steel. Join molybdenum metals in cast iron, iron can improve the strength and wear resistance. Nickel-base superalloy containing 18% molybdenum have high melting point, low density and thermal expansion coefficient and other characteristics, used in the manufacture of various high-temperature aerospace components.

Molybdenum mine located

For our Molybdenum mine located in central and southern molybdenum reserves accounted for 35.7%, ranking first. Followed by the Northeast region 19.5% 14.9% northwest, east and 13.9%, 12% in North China, while only 4% of the southwest. In the provinces (regions), Henan retain up, the country's total reserves of molybdenum, followed by Shaanxi, Jilin, 13.6%, 29.9%, accounting for 13%. More provinces (regions) Additional reserves: Shandong accounted for 6.7%, 6.6%, Hebei, Jiangxi, 4%, 3.7%, Liaoning, Inner Mongolia, accounting for 3.6%. More than eight provinces (regions) of the total reserves of the country's total reserves of molybdenum, of which the top three in Henan, Shaanxi, Jilin and other provinces accounted for 56.5%, about 81.1%.

The molybdenum element

Molybdenum is an essential trace element the human body, animals and plants. Silver-white metal, hard and tough. Human various organizations molybdenum total adult body is 9mg, liver, kidney highest content. Basic introduction Molybdenum is a transition element, easily changing its oxidation state in the oxidation-reduction reaction of the body plays a role in electron transfer. In oxidized form, molybdenum is likely to be in the +6 valence state. Although during the electron transfer it is also likely to be restored first as a valence state. However, the reduction in enzyme has been found after the other oxidation state of molybdenum. molybdenum is a xanthine oxidase / dehydrogenase, aldehyde oxidase and sulfite oxidase components, which indeed know the human body and trace elements necessary for plants and animals.

How to prevent oxidation of molybdenum electrodes

Pure molybdenum for the problem of easily oxidized at high temperatures, developed a kiln when roasted molybdenum electrodes to prevent oxidation of the glass-based coating. The coating is barium silicate glass as the main Cr2O3 the refractory filler added organic binder , with terpineol as solvent to prepare a suspension , applied by brush method molybdenum electrode surface. the effect of the amount of Cr2O3 on the oxidation resistance of the coating by spectroscopy (EDS) and thermostatic gravimetric analysis , when compared coated and uncoated protection , the difference molybdenum substrate surface oxygen content. the results show that the coating over a wide temperature range for molybdenum metals electrodes have good protection.

The main component of molybdenum electrodes

The main component of molybdenum electrodes are molybdenum, obtained by powder metallurgy process. Internationally molybdenum electrode ingredients 99.95% and a density greater than 10.15g / cm3, in order to ensure the quality and life of the glass electrode. Common molybdenum metals electrode sizes from 20mm diameter to 152.4mm, single length can reach 1500mm.
Molybdenum electrodes to replace the existing heavy oil and gas energy, can effectively reduce the pollution of the environment, provide quality glass.

What is Molybdenum Electrodes

Molybdenum Electrodes for its high temperature strength, high temperature oxidation resistance, long life, corrosion resistance and easy to color the glass, etc. are widely used in household glass, optical glass, insulation materials, glass fiber, rare earth industry and other fields, the electrodes the diameter of 10 ~ 100mm, a length 150 ~ 1500mm .

As we all know molybdenum metals have high temperature strength, high temperature oxidation resistance, long life, based on these advantages, it is usually used in household glass, optical glass, insulation materials, glass fiber, rare earth industry and other fields.
