Preparation of zinc aluminate spinel ZnAl2O4 by corrosion synthesis in ethanol

ZnAl2O4 was obtained by corrosion synthesis which produced mixtures of zinc alkoxide by metallic zinc dissolution in ethanol and aluminum ions by addition of aluminum chloride as a catalyst. The corrosion product became ZnAl2O4 when the mixtures were hydrolyzed, pH-adjusted, and fired at temperature higher than 873 K. It is shown that the ZnAl2O4 powder has the particle size distribution of 0.4 to 10/μm. It is considered that the corrosion synthesis of a ZnAl 2O4 production has some features of fast reaction in ethanol and well blending circumstances in ion size level condition.
