Parameters index:, bulk density: 0.83g / m3 particle size (D50): 50nm specific surface area: 17.56m2 / g theoretical density: 4.2g / m3 Appearance: blue-green powder Shelf Life: 6 months to save the product performance under dry conditions : reduction of nickel hydroxide hydroxides, and some strong oxidant can react NiO (OH), there is a strong alkaline, as the strong base, in a saturated aqueous solution (mass ratio of 5% concentration) can be ionized in small amounts of a large number of OH- and [Ni (OH) 6] 4- anion, and can be dissolved in NaOH, KOH, etc. is formed alkali Na4 [Ni (OH) 6] or K4 [Ni (OH) 6], obtained after evaporation to dryness Na4NiO3 so easy hydrolysis of salts. Application: 1. Preparation 2. Preparation of raw nickel salt alkaline storage battery 3. plating, nickel composite plating 4. Various catalysts in industrial production
