Abstract

Abstract The conditions of formation of copper(II)-zinc(II) hydroxide nitrate mixed crystals Zn xCu 2−x(OH) 3NO 3 (0<x≤1.8), precipitated from nitrate solutions with alkali, have been established. It was found that the decomposition of the mixed crystals to an oxide product is a topotactic process. Under mild conditions of decomposition a saturated solid solution of Cu(II) in ZnO is formed as an intermediate phase that finally stratifies to CuO and to the solid solution with a lower copper content.
