| Nickel fluoride Usage And Synthesis |
| Chemical Properties | Nickel(II) fluoride has the tetragonal rutile structure with only slightly tetragonally compressed NiF6 octahedra; the Ni-F distances being 2.01 and 1.98 ?. Above the melting point it sublimes as a linear gaseous molecule. The anhydrous fluoride is rather unreactive towards concentrated acids; it is only slightly soluble in anhydrous hydrogen fluoride and is not attacked by electronegative elements such as chlorine, sulphur and phosphorus. The pale green tetrahydrate is slightly soluble in water; when heated, several intermediate hydrates are formed prior to N1F2. |
| Chemical Properties | Green crystalline powder |
| Uses | Nickel fluoride?comprises the passivating surface that forms on nickel alloys, e.g. monel, which is why such materials are good to store or transport hydrogen fluoride or elemental fluorine. |
| Preparation | Nickel fluoride tetrahydrate [13940-83-5], NiF2.4H2O, |
The preparation process of nickel fluoride tetrahydrate mainly includes four steps: nickel carbonate slurry preparation, synthesis preparation, purification and impurity removal, washing, filtering and drying.
Nickel carbonate slurry: Pure water is used to slurry nickel carbonate, with a liquid-solid ratio generally between 3:1 and 4:1.
Synthesis preparation: Heat the slurry of nickel carbonate to 75 ° C to 90 ° C, and then add ammonium fluoride. The amount of ammonium fluoride added should be 1.25 to 1.4 times the mass of nickel carbonate to ensure an excess of ammonium fluoride. React at this temperature for 2 to 3 hours to complete the synthesis process 12.
Purification and impurity removal: After the synthesis reaction is completed, add soluble carbonate as an auxiliary material and continue to react at 75 ° C to 90 ° C for 1 to 2 hours to purify and remove impurities.
Wash, filter and dry: After purification and impurity removal, filter the formed nickel fluoride precipitate. The filtrate can be returned to the next nickel carbonate slurry process, while the filter cake is washed 2 to 3 times, filtered, and dried to ultimately obtain nickel fluoride tetrahydrate product 2.
In the preparation process, strong corrosive substances such as fluorine gas and hydrofluoric acid are not used. Therefore, compared with traditional processes, this preparation method has the advantages of high safety, low equipment requirements, easy operation, and high product quality
