What is molybdenum powder? Molybdenum powderis hard and ductile. It still has high strength at very high temperatures. It is stable in air at normal temperatures and burns to produce molybdenum trioxide at high temperatures. It can be combined with chlorine and bromine. It is insoluble in hydrochloric acid and hydrofluoric acid. It can dissolve in concentrated sulfuric acid, nitric acid and aqua regia, and its appearance is dark grey. The colour should be uniform, without agglomeration and visible inclusions. In addition, molybdenum powder can be divided into light molybdenum powder (PCC) and molybdenum powder (GCC). Molybdenum powder is characterized by its colour, particle size, surface properties, dispersion, rheological property, thixotropy and crystal form can be manually controlled. Moreover, molybdenum powder has high chemical purity, strong chemical inertness, good thermal stability, and will not decompose below 400 ℃ In addition, molybdenum powder has the advantages of low oil absorption rate, low hardness, small wear value, non-toxic, odourless, tasteless, and good dispersion.
Preparation method of molybdenum powder In industrial production, molybdenum trioxide can be reduced with hydrogen to produce molybdenum I or secondary ammonium molybdate can be treated with acid or decomposed by heating to obtain molybdenum trioxide and then reduced with hydrogen in a tubular electric furnace. Carbon can also be reduced to molybdenum powder, but the purity is poor. In the first stage, molybdenum trioxide is heated at 450~700 ℃, then reduced in the second stage at 900~1100 ℃ to obtain finished molybdenum powder.
Use of molybdenum powder The fool is used for large slabs and is the raw material of molybdenum silicide electric heating element. Fmo-2 is used for silicon-controlled wafers, molybdenum tips and other raw materials. It can also be used in powder metallurgy materials, building materials, chemistry, and petroleum. Molybdenum is one of the essential trace elements for plants and is used as a trace element fertilizer in agriculture..
Safety of molybdenum powder Molybdenum powder can burn or explode when exposed to high heat and react strongly with oxidants to form molybdenum oxide. The product is packed in a clear polyethene plastic bottle, the bottle cap should be tightened, and the plastic bottle should be placed in a wooden box and secured with soft objects around it. Or the product should be packed into an iron bucket lined with polyethene plastic bags, each box (bucket) with a net weight of 30kg. The wooden box or iron bucket should have the words "moisture proof", "fragile", and "upward". The product should be stored in a dry, ventilated warehouse free of acid and alkali atmosphere and protected from oxidation. The product should be protected from rain and moisture during transportation, and The package shall not be severely collided to prevent damage to the package. The storage period of molybdenum powder shall not exceed half a year. When the skin or eyes come into contact with molybdenum powder, wash it with soap and clean water. If it is serious, go to a doctor. Drink an appropriate amount of water to induce vomiting when ingesting it. In case of fire, use a dry powder fire extinguishing agent to rescue.
Price of molybdenum powde Molybdenum powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of molybdenum powder. A large amount of large amount will be lower. The price of molybdenum powder can be found on our company's official website.
