-99 is one of the radioactive isotopes of molybdenum molybdenum, he used for the preparation of technetium -99 in the hospital. Technetium -99 is a radioactive isotope, the patient for visceral angiography can be taken after. The molybdenum -99 used for this purpose is usually stored in a relatively small container after the oxidation of aluminum is absorbed. When the Mo -99 decay generated technetium -99, when necessary, to take out the technetium -99 from the container to the patient. Molybdenum density 10.2 g / cubic centimeter. Melting point 2610. Boiling point 5560. +2, +4 and +6 valence, stable price of +6. Molybdenum is a transition molybdenum concentrate elements, easy to change the oxidation state and in vivo oxidation reduction reaction plays the role of electron transfer. In the form of oxidation, molybdenum is likely to be in the +6 state. Although it is likely to be reduced to +5 at the time of the electron transfer, the other oxidation state of molybdenum in the enzyme has been found to be in a state of molybdenum. Molybdenum is xanthine oxidase / dehydrogenase, aldehyde oxidase and sulfite oxidase components to know for sure the human body and trace elements essential to plants. Natural molybdenite MoS is a soft black mineral, similar in appearance and graphite. Before the end of eighteenth Century, both in the European market to sell molybadenite name. In 1779, Scheler pointed out that graphite and molybadenite are two completely different substances. He found that nitric acid had no effect on graphite, but with the molybadenite reaction, obtained a kind of white powder, which was a kind of white powder, and it was co boiling with alkali solution, crystallization precipitation of a kind of salt. He believes that the white powder is a metal oxide, with a mixture of charcoal after strong heat, not to get metal, but with a total of sulfur after the molybadenite. In 1782, a Swedish mine main Elmo from molybadenite isolated metal named for molybdenum and symbolic elements set to Mo. We translated into molybdenum. It has been acknowledged that Betsey et al.. Molybdenum is mainly used for the steel industry, the most is to molybdenum oxide pressure block for steel or cast iron, less melting into molybdenum molybdenum foil Then used in steel. The molybdenum content in low alloy steel is not more than 1%, but the consumption of this aspect accounts for about 50% of the total consumption. Stainless steel, can improve the corrosion resistance of steel. Adding molybdenum in cast iron can improve the strength and wear resistance of iron. Containing 18% molybdenum nickel based super alloy with high melting point, low density and low thermal expansion coefficient and other properties for various high temperature components of the aviation and aerospace manufacturing. Metal molybdenum is widely used in electronic devices such as electronic tubes, transistors, and rectifiers. Molybdenum oxide and molybdate are excellent catalysts in the chemical and oil industries. MoS2 is an important lubricant, used in aerospace and mechanical industry. Molybdenum is one of the essential trace elements in plants, and is used as a trace element fertilizer in agriculture. Pure molybdenum wire used for high temperature electric furnace and electric spark machining also wire cutting processing; molybdenum piece used to manufacture radio equipment and X ray equipment; molybdenum high temperature molybdenum crucible Ablation, mainly used in the manufacture of gun bore, the rocket nozzle, the light bulb filament support. Molybdenum can increase the elastic limit, corrosion resistance, and maintain permanent magnetism in the alloy steel, molybdenum is one of seven kinds of trace elements in plant growth and development. Animals and fish, like plants, need to be molybdenum. The application of Mo in the field of other alloys and chemical industry is also increasing. For example, molybdenum disulfide lubricant is widely used in various types of machinery lubrication, molybdenum metal gradually applied in nuclear power, new energy and other fields. Due to the importance of molybdenum, the national government as a strategic metal, molybdenum in early twentieth Century was heavily used in the manufacture of weapons and equipment, modern high, fine, sharp equipment requirements higher, such as molybdenum and tungsten, chromium, vanadium alloy used in the manufacture of warships, rockets, satellites, alloy components and parts.
