Abstract

This article describes the methods for producing zinc oxide. The methods of chemical precipitation, sol-gel, gas deposition, magnetron deposition, and a comparative characteristic are also considered. Calculations of the solution – precipitate equilibrium were performed. Precipitation potentiometric titration of zinc salts with several precipitants was carried out. The constructed curves in the coordinates of the concentration ratio of precipitant/cation – pH were used to determine the optimal ratios of the reagents.
