Green Crystal. Melting Point: 56.7 ℃; Boiling Point: 137 ℃;d 2. 05. Deliquescence. Microweathering in dry air. Dissolved in 0.4 water, the solution is acidic, pH value of about 4. Soluble in ethanol, slightly soluble in acetone. Mixed with reducing agent, organic matter, combustible or metal powder can form explosive mixture, explosion can occur when heated sharply.
water was added to nickel carbonate, and the mixture was stirred uniformly. Then, nitric acid was gradually added, filtered, the filtrate was evaporated, cooled, and the crystals were precipitated by Suction filtration.
It is used for electroplating nickel-chromium alloy, manufacturing other nickel salts and nickel-containing catalysts, storage batteries, and metal surface treatment agents.

toxic, long-term contact with the skin can cause eczema, scabies, follicular papules, edema, erythema, skin damp. Eating nickel nitrate by mistake can cause poisoning.
The maximum allowable concentration of nickel salt (based on nickel) in the form of water aerosol is 0.0005mg/m3.
Production personnel should wear anti-virus masks, work clothes and latex gloves to prevent direct skin contact to the maximum extent. Take a shower after work.
Chemical properties Green monoclinic crystal system. Relative density 2.05. Melting point 56.7 ℃. Boiling point 136.7 ℃. Easily soluble in water, liquid ammonia, ammonia, ethanol, slightly soluble in acetone. Its aqueous solution is acidic (Ph = 4). It has moisture absorption, rapid deliquescence in humid air, and slightly weathered in dry air. 4 crystal water is lost when heated, and when the temperature is higher than 110 ℃, it will decompose into basic salt, and continue to heat to form a mixture of brown-black nickel trioxide and green nickel oxide. Contact with organic matter can cause combustion and explosion. Toxic.

production method: 64 kg of nickel is put into the reaction kettle, a certain amount of water is added, and 188 kg of concentrated nitric acid is added dropwise under stirring. After dropping, slowly heat up and react under heating until no gas is released. Stop reacting. Add nickel phosphate to adjust the pH value to about 5~6. Statically filtered, the filtrate is concentrated, cooled and crystallized, centrifugally dehydrated and dried to obtain the finished product.
production method the nickel metal method rinses the nickel plate with water, adds it to the reactor according to the theoretical amount of 110% ~ 115%, then adds a certain amount of water, and then slowly adds concentrated nitric acid to control the reaction not too intense. Keep the reaction at 50~60 ℃ for 3~5h until no yellow smoke is produced. Then dilute the reaction solution with water to about 26 ° Bé, adjust the pH = 5~6 with nickel carbonate, let stand, and filter. The clear liquid is acidified with nitric acid to pH = 3~4, and then concentrated to 56~57 ° Bé by vacuum evaporation, then cooled and crystallized, centrifuged to obtain nickel nitrate finished product.

The nickel hydroxide method acidulates nickel-containing industrial waste (such as electroplating hangers) with waste hydrochloric acid (15~16 ° Bé) and waste nitric acid (27 ° Bé) to obtain a nickel chloride solution, but this solution contains iron, Copper, chromium plasma, can add sodium chlorate to remove iron, add soda to remove copper. If there is more chromium, nickel hydroxide can be added, and the pH of the solution can be adjusted to 4.6~4.8 to precipitate chromium hydroxide. Then, caustic soda is added to the refined nickel chloride solution, and the pH value is adjusted to 8~10, that is, nickel hydroxide precipitate is precipitated, rinsed to be neutral, a large amount of sodium ions are removed, and crude nickel hydroxide is obtained by pressure filtration. Add it to a human acid-resistant reactor, then slowly add dilute nitric acid to the reaction solution pH4 ~ 5 to generate nickel nitrate solution. After clarification and filtration, the obtained filtrate is then passed into hydrogen sulfide gas to remove Cu2 +, Pb2 +, Zn2 + and other impurities in the solution, add nickel carbonate to adjust the pH value to 5, then filter, add hydrogen peroxide to the filtrate to remove iron, filter, and add barium nitrate. Then it is heated to boiling with steam, clarified and filtered, and the clear liquid is evaporated and concentrated, cooled and crystallized, and centrifuged to obtain a finished nickel nitrate product.
