Nickel Nitrate green solid inorganic compound. Chemically all nitrates are OXIDIZING agent. Nickel Nitrate anhydrous form is not commonly encountered, thus “nickel nitrate” usually refers to nickel(II) nitrate hexahydrate.Application: NICKEL Nitrate hexahydrate most commonly used in Battery Manufacturing Industries and as a OXIDATION catalyst.Dose: It is used in nickel plating and to make nickel catalysts for use in chemical manufacture.Note: Nickel nitrate is a green crystalline solid. It is soluble in water. It is noncombustible, but it will accelerate the burning of combustible materials.
