Technical characteristics
Nickel powder is manufactured out of aqueous-salt nickel solutions by electrolytic method with further thermal processing and drying in reducing environment. Another method is carbonyl. It foresees an intermediate obtaining of carbonyl nickel and its further destruction. Highly-dispersed Ni contains chromium, tungsten, copper and other components. It is used in the capacity of plasma spaying in aviation, CCD, for manufacture of
accumulator electrode plates, powder metallurgy, for component recovery. Such coverings obtained at spraying have a high density and resistance.

Range of products
Powder carbonyl nickel is designated as PNK. It is obtained by carbonyl method. Nickel powder PNE is made by electrolytic method. Ultra-fine powder nickel is usually made to advance orders as long as a process of its manufacture is very difficult. Besides, there is nickel powder that is used in building mixes and thermal insulating materials, ceramics. Granulated or self-fluxing powder that contains Ni is used for assuming the super strength for goods of different shapes and sizes. Such composition is applied by method of gas-powder deposit welding. When choosing powder nickel, it is necessary to decide on dimensions of particles that will be made for order in advance or according to GOST.
