The Nickel powder. Brand chemical composition.
Nickel powder produced by the electrolytic method from aqueous salt solutions of Nickel, with subsequent heat treatment and drying in a reducing environment. Another way is carbonyl, which provides for the intermediate obtaining of Nickel carbonyl and its subsequent decomposition. Particulate Ni in its composition contains chromium, tungsten, copper, and other components. He applied as a plasma spray aviation, TBG, for the production of battery electrode plates, powder metallurgy for the recovery of parts. Such coatings, obtained by sputtering, have a high density and durability.

Powder of Nickel carbonyl denote PNK, carbonyl method. Nickel powder pne are produced by the electrolytic method. Ultrafine Ni powder is usually made on a preliminary application, because its production process is very time consuming. In addition, there is also a Nickel powder, which is used in building materials and insulating materials, ceramics. Tamifluswine granular or powder which contains Ni, is used to make special high strength products of different shapes and sizes. This composition is applied by the method of gas-powder surfacing. Choosing the powder, it is necessary to determine the particle sizes that can be made upon request and according to GOST.
