説明
Multiorganometallic compounds made by modifying the synthetic method studied by Thomas were used to prepare high purity submicron-size MgAl2O4 powders. Hydrolytic decomposition of MgAl2(i-OC3H7)8 and the subsequent calcination process produced submicron powders of MgAl2O4 of more than 99.98+% purity: 50Å to 100Å at 800°C and about 0.1μm at 1200°C, and with purity of 99.98+% The major contaminant was Si from silicon grease. Homogeneity and stoichiometry of the powders after calcination were studied by transmission electron microscopy and chemical analysis. X-ray and infrared analyses indicated that the formation process of MgAl2O4 from MgAl2(i-OC3H7)8 depends strongly on the atmosphere in hydrolysis of MgAl2(i-OC3H7)8 and the subsequent calcination temperature.
