Ammonium molybdate

Ammonium molybdate (ammonium molybdate) is powdered crystal of white or yellow. During the chemical studies of the ammonium molybdate plays an important role as monovalent metals in chemical compounds. Such properties of molybdate ammonium is one of the most convenient of chemicals with a wide range of applications.

When interacting with water, a reaction takes place full solvolysis (solubility – 400 g/l at 20 °C). In ethyl alcohol and acetone insoluble, but dissolves in strong acids and alkaline media. Solution in nitric acid called molybdenum liquid. Contacting with air masses and decays due to the loss of ammonia. Heat to 150 °C lead to the decomposition of three main components: molybdenum, water, and ammonia. Molar weight – 196,01 g/mol, density – 2.27 g/cm3. Formula – (NH4)2MoO4.

The synthesis of the substance is carried out by mixing the metilkarbinolom and concentrated ammonia solutions of dioxomolybdenum, technical molybdenum trioxide.

Ammonium molybdate is widely addressed application. He demanded in metallurgy (manufacture molybdenum wire ribbons, sheets, rods, powder...), biochemical laboratories, processes Hydrotreating, in the manufacture of electrical equipment, obtaining ultrapure molybdenum and its alloys. In electron microscopy, performs contrast component. They oxidenot aluminum and aluminum alloys, resulting in surfaces formed a special black film, giving the chemical resistance of parts to aggressive media, attractive, and appears the basis for painting. Textile production requires molybdate ammonium as in a staining material, chemistry, as an important component for creating coatings.

One of the main consumers of the salt – agricultural complex, where it as a Supplement enriched with molybdenum is introduced into the feed and use as fertilizer. The introduction of ammonium molybdate is mainly when seedbed manipulation of seeds and foliar fertilization of the plants. Culture which are most in need of this substance: legumes (helps to absorb nodule bacteria of atmospheric nitrogen), cauliflower, carrots, beets, tomatoes, flax, buckwheat (to increase productivity), as well as conifers. Where the absorption of molybdenum bad (acidic soddy-podzolic and gray forest soils), soil limed.
