Abstract
NiAl2O4 was tried to make by metallic corrosion with chloride as a catalyst in ethanol. As synthesis of NiAl2O4, two ways were carried out: ①nickel was corroded with addition of aluminum chloride, and ②aluminum was corroded with nickel chloride. The corrosion products obtained by two methods were hydrolyzed, adjusted pH and then fired. It was found that the powder fired at 1073 K and over by two methods was of NiAl2O4 spinel whose diameter was 0.4 to 30 µm. The above results were considered as electrochemical and corrosion phenomena.
