- not soluble in alcohol and acetone;

- a density 2.498 g/смᵌ;

- soluble in water: 400g/l (20 ᵒС).

Application

Ammonium molybdate is intended for the production of wire, rods, strips, tapes, for Hydrotreating catalysts, production electrical equipment, high-purity molybdenum and hard alloy, and in the production of premixes for supplements of the trace mineral, molybdenum feed.

In the oil industry used to abessinia or production of hydrogenation catalysts, metallurgy for the production of tapes sheets, powder.
One of the main consumers of the salt – agricultural complex, where it as a Supplement enriched with molybdenum, is introduced into feed and use it as fertilizer. The introduction of ammonium molybdate occurs primarily through the manipulation of pre-sowing seeds and foliar feeding of plants. Crops that are most in need of this substance: legumes (helps to absorb nodule bacteria atmospheric nitrogen), cauliflower, carrots, beets, tomatoes, flax, buckwheat (increase productivity), as well as conifers.

In agriculture it is used as microdamage molybdenum. Ammonium molybdate is used mostly for pre - dusting seeds. The rate of seeds on 1 m2 consumes only 3-5 mg molybdate of ammonium. For foliar feeding (spraying the plants) used 0,01-0,03 % solution. Paid mostly under legumes.

This substance belongs to the 3rd class of danger at the the effect on the human body. Fire and explosion proof. In the air and water environments of toxins are formed. The organism enters through the respiratory and gastrointestinal tract, after that, it can be deposited in bone, liver, and kidney. Below to avoid the accumulation of ammonium in the body, work with it, you need to perform a respirator in a well ventilated area.

Typically, this reagent is Packed in bags with capacity of 25 kg. Transported by railway, car and water vehicle with a mandatory limit of penetration moisture and damage to the container. Keep it recommended in a closed cool and dry warehouses. The shelf life is 1-3 years.
