Abstract:
The influence of the electrolyte composition on electrolytically synthesized zinc compound powders has been studied. It has been shown that if an electrolyte made by dissolving Na$_{2}$S$_{2}$O$_{3}\cdot$5H$_{2}$O is kept at room temperature, a mixture of zinc sulfide and hydrozincite is obtained. An electrolyte containing Na$_{2}$SO$_{3}$ or Na$_{2}$S$\cdot$9H$_{2}$O gives a mixture of hydrozincite with zinc oxide and/or with zinc sulfide. The size of nanocrystals has been determined. It has been found that hydrozincite decomposes into zinc oxide, water, and carbon dioxide in the temperature range of 200–250$^{\circ}$C.
