Nickel(II) sulfate 7786-81-4 Nickel sulfate - Preparation Method
Open Data Verified Data
- metallic nickel method: water was added to the reactor, and then sulfuric acid was added to form 30be, metallic nickel was further added, and nitric acid was added in fractions to carry out the reaction. The reaction concentration reached 48~50. When Be, crystallize and filter, wash the crude crystals with water and add water to dissolve into 30Be, then add barium carbonate to neutralize the free acid, and then add hydrogen peroxide to oxidize the divalent iron and hydrolyze it, after clarification of the purified solution, a small amount of sulfuric acid is added to adjust the pH value to 3~4, and then the crystal is concentrated and centrifuged for dehydration to prepare nickel sulfate.
- recovery method: the electrolytic waste liquid in the copper smelting process is purified, crystallized and dehydrated, and nickel sulfate can be obtained.
- preparation of nickel sulfate from cobalt-producing nickel-containing waste liquid: first, nickel carbonate is precipitated from a spent nickel sulfate solution produced from a cobalt salt using a soda ash solution, and then nickel carbonate is dissolved in sulfuric acid to prepare nickel sulfate.

packed in a woven bag or barrel lined with polyethylene plastic bag, each bag (barrel) has a net weight of 25kg and 50kg. There should be a marked "drug" sign on the package. Store in a cool, dry, ventilated warehouse. Do not store under active chlorine and hot sun. Take it lightly to prevent package breakage. Do not store and mix with food. During transportation, attention should be paid to heat and moisture protection. Nickel salts can damage human skin, and metallic nickel and its compounds can disrupt cellular metabolism. The maximum allowable concentration: the oxide and sulfide of divalent and trivalent nickel (calculated as Ni) is 0.5mg/m3; The nickel salt in the form of water aerosol (calculated as Ni) is 0. 0005mg/m3. The operator should wear a gas mask and a hose.

Nickel(II) sulfate 7786-81-4 Nickel sulfate - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | nickel sulfate has three types: anhydrous, hexahydrate and heptahydrate, there are two variants of the α-form and the β-form, the former being a blue tetragonal crystal and the latter being a green monoclinic crystal. According to the product classification, it can be divided into electroplating grade nickel sulfate and battery grade nickel sulfate. The former is used in electroplating industry and battery industry, is the main nickel salt of nickel plating and chemical nickel, and is also the source of metal nickel ion, the nickel ions and sulfate ions can be dissociated in the electroplating process. Battery grade nickel sulfate is one of the important raw materials for the production of ternary precursors, and different types of precursors have different nickel contents, which requires different amounts of battery grade nickel sulfate. The biggest difference between electroplating grade nickel sulfate and battery grade nickel sulfate is the cobalt content, battery grade cobalt content requires a lower threshold, the content requirement is only 0.4% (nickel 22.2%, cobalt 0.4%), because nickel sulfate as a ternary battery precursor raw material manufacturing, also need to use cobalt sulfate and other cobalt-containing salts, and electroplating grade nickel sulfate application of the downstream surface treatment industry, cobalt is used as an impurity element, its content needs to be reduced, the cobalt content should not exceed 0.05% (nickel 22.2%, cobalt 0.05% Max) Electroplating grade nickel sulfate is mainly used in the production of automobile hub, external components and other products. |
| application field | The main application fields of nickel sulfate are as follows: 1, used in electroplating industry, it is the main nickel salt of nickel plating and chemical nickel, and also the source of metallic nickel ions, which can dissociate nickel ions and sulfate ions in the electroplating process. 2, hardened oil production is the catalyst for oil hydrogenation. 3, the pharmaceutical industry for the production of vitamin C oxidation catalyst. 4, inorganic industry used in the production of other nickel salts such as: Nickel Sulfate, nickel oxide, nickel hydroxide, nickel carbonate, etc. 5, in the printing and dyeing industry, nickel sulfate is used as mordant for the preparation of phthalocyanine brilliant blue complexing agent and vat dye. Among the above-mentioned applications in many industries, the use of electroplating, electroless plating and rechargeable batteries is the largest, and the battery grade consumption accounts for about 50% of the total demand. |
| battery grade nickel sulfate | nickel sulfate is mainly divided into electroplating grade nickel sulfate (nickel 22.2%, cobalt 0.05% max) and battery grade nickel sulfate (nickel 22.2%, cobalt 0.4%), which is mainly divided by the content of cobalt element. The former is mainly used in the surface treatment industry; The latter is mainly used in the new energy battery material industry. 1. Application of battery grade nickel sulfate in nickel metal hydride and nickel cadmium secondary batteries. Nickel sulfate can be used to make spherical nickel hydroxide, which is an important raw material for cathode materials of nickel hydrogen and nickel cadmium secondary batteries. But the method with the nickel hydrogen battery low energy, no use with the charge, the use of inconvenience; Nickel cadmium battery, containing heavy metal cadmium. This type of battery has gradually fade out of the market trend. 2. Battery grade nickel sulfate is used to prepare nickel cobalt hydroxide (NC). The market has NC products containing 60% nickel, 5% Cobalt and 35% hydroxide. 3, battery grade nickel sulfate for the preparation of nickel cobalt aluminum hydroxide (NCA), the representative product is a ternary lithium ion battery (referred to as NCA18650) produced by Japan's Matsushita for Tesla, which is a cylindrical nickel cobalt aluminum ternary lithium battery with a diameter of 18mm and a length of 65mm. NCA is an important component of the positive electrode material of the Tesla battery. 4, battery grade nickel sulfate for the preparation of nickel cobalt manganese hydroxide, commonly known as the ternary precursor (referred to as NCM), the representative model has NCM-523, NCM-622, NCM-811, etc., including digital 523, 622, 811 represent the proportion of three elements of nickel cobalt manganese. |
