Molybdenum rod
Divided forged molybdenum rod and polished molybdenum rod. The surface of forged molybdenum rod is allowed to have oxidized see and slight forging rolling trace, the surface of polished molybdenum rod is metallic luster, no significant oxidation phenomenon.
Used for manufacturing electric vacuum parts, guide rod, electrode, lead wire, heating electronic components, electronic tubes, electric light source lead wire support, side rod, core wire, etc.
Molybdenum rod should be prevented from moisture and violent collision during transportation. The product should be stored in dry ventilated, dry and no acid and alkali atmosphere, strictly prevent oxidation, storage period should not exceed 6 months.
Molybdenum is a chemical element whose chemical symbol is Mo. It has an atomic number of 42 and is a gray transition metal. The pure metal of molybdenum is silvery white and very hard. Steel can be hardened by adding a small amount of molybdenum to it. Molybdenum is an important nutrient for plants and is also found in some enzymes. Molybdenum-99 is one of the radioactive isotopes of molybdenum that he uses in the hospital to prepare technetium-99. Technetium-99 is a radioactive isotope that can be used for imaging internal organs in patients. Molybdenum-99 for this purpose is usually absorbed with alumina powder and stored in relatively small containers. When molybdenum-99 decays, it forms technetium-99, which can be removed from the container and given to the patient if needed.
The density of molybdenum is 10.2 g/cc. Melting point is 2610 ℃. The boiling point of 5560 ℃. The valence is +2, +4 and +6, and the stable valence is +6. Molybdenum is a kind of transition molybdenum powder, which can easily change its oxidation state and play the role of electron transfer in REDOX reaction in vivo. In the oxidized form, molybdenum is most likely in the +6 state. Other oxidation states of molybdenum have been found in reduced enzymes, although it is also likely to be first reduced to the +5 state during electron transfer. Molybdenum is a component of xanthine oxidase/dehydrogenase, aldehyde oxidase and sulfite oxidase, so it is known to be an essential trace element for human body, animals and plants.
