Application of Molybdenum Powder

By the rapid development of the application of molybdenum powder, has been widely used in industrial and agricultural areas, such as rubber, plastic, papermaking, coating, paint, printing ink, cable, pharmaceutical, chemical fertilizer, feed, food, sugar, textile, glass, ceramics, sanitary products, sealant, adhesive, pesticides and pesticide carrier and flue in addition to the environmental aspects, such as sulfur, water treatment. Lightweight aluminum overlap with aluminum powder is also have different purposes, is mainly used in papermaking, plastics, synthetic rubber, food, edible pigment, medicine, adhesives and hygiene kits, and other fields. In recent years, because of the information about light molybdenum powder can enhance the properties of some materials, so an increase in the scope of its use.

Production Process of Molybdenum Powder

Production Process of Molybdenum Powder

In industrial production of molybdenum powder, molybdenum trioxide or ammonium molybdate is reduced by hydrogen gas with dew point temperature below -25℃. When ammonium molybdate is used as raw material, it is calcined in resistance furnace or rotary tube furnace, the temperature is controlled at 500 ~ 600℃, and the product after calcined is yellow or white molybdenum trioxide powder. The roasted molybdenum trioxide was firstly reduced by hydrogen in a tubular resistance furnace, and the reduction temperature was controlled at 450 ~ 650℃. The product was dark brown molybdenum dioxide powder.The reduced molybdenum dioxide powder is rereduced by hydrogen in a tubular resistance furnace. General reduction temperature is controlled in 850 ~ 950℃, the product is gray metal powder,In industrial production, roasting and primary reduction are also combined, and the temperature is controlled at 500 ~ 600℃. Molybdenum powder with high purity and fine particle is usually prepared by reducing molybdenum chloride with hydrogen.

Features of Molybdenum Powder

Features of Molybdenum Powder

  • 01.

    Molybdenum powder can be divided into light molybdenum powder (PCC) and molybdenum powder (GCC). The characteristics of molybdenum powder can be manually controlled color, particle size, surface characteristics, dispersion, rheology, thixotropy and crystal type.

  • 02.

    Molybdenum powder has high chemical purity, strong chemical inertia, good thermal stability, will not decompose below 400 degrees Celsius.

  • 03.

    Molybdenum powder has the advantages of low oil absorption rate, low hardness, small wear value, non-toxic, odorless, tasteless, good dispersion and so on.
