Аннотация: An anion-exchange method for synthesizing nickel hydroxide using industrial strongly basic AV-17-8 anionite has been proposed. The influence of conditions (concentration and nature of starting salt, amount of the anionite, process duration, etc.) on the precipitate yield has been established. The product has been investigated by scanning electron microscopy, IR and Raman spectroscopy, X-ray phase analysis, and thermal and chemical analyses. It has been established that the product is a disordered layered modification of nickel hydroxide alpha-Ni(OH)(2), which contains anions and water molecules in the interlayer spacing. Nickel hydroxide particles are needle crystals (40-80 nm) that form agglomerates 0.3-0.5 mu m in size.
