Nickel powders

Nickel electrotechnical powders are made by the electrolytic expedient of water solutions of salts of nickel with the subsequent drying and heat treatment in regenerative medium.

Electrotechnical powder

Nickel powders are applied:

in magnetic character metallurgy;
in technological processes of manufacturing of electrode plates of alkaline accumulators, porous filtrating materials, magnets, electrical links;
in processes of restoration of iznoso-steady coats on details of aviation drives methods of a plasma dusting.

The following nickel powders are produced and distributed by UEIP:

Powder type	Mean particle diameter and size distribution median, micron*	Specific area, m²/g**	Bulk density, g/cm³	Phase composition of the powders
АПН	12,5/10,9	1,0-3,2	1,2-1,4	Ni, NiO
А-1	17,5/15,0	0,5-0,6	1,4-1,6	Ni
А-2	19,6/17,5	0,5-0,6	1,4-1,6	Ni

* determined by sedimentation

** determined by BAT

Nickel powders are electrochemically produced from aqueous solutions of nickel nitrate with subsequent drying (АПН type) and heat treatment in reducing atmosphere (A-1, A-2 type).
