摘要：

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.
