It is gray and irregular shaped powder, easily oxidized in moist air. Nickel Metal Powder ( Fine Grade) is considered corrosion-resistant because of it's slow rate of oxidation. This metal powder exhibits a state of very high purity and good sphericity. It is employed in the synthesis of a metal-rich layered telluride, TaNi2Te2 for photovoltaic applications. This powder is ideal to suppress mechanical parts, structural parts and welding materials. Nickel metal powder ( Fine Grade) is produced from nickel cathode or nickel briquette, usually having purity of 99.50% min. It finds application in powder metallurgy, pharmaceutical and welding electrodes.
