Abstract
Spinel structure MgA12O4 is an important compound oxide for de-sulfur catalysts or electronic devices. There had been proposed so many-kinds of synthesis routes for MgAl2O4, however, it is still very difficult to get a pure and stoichiometric MgAl2O4 powder with high specific surface area. The authors approached by using atmospheric solvothermal synthesis with mixed nitrate solution adding monomer, dimer and trimer of glycol. The MgAl2O4 powder was successfully synthesized by the process and the glycols were recognized to play an important role of the reduction agent of nitric acid group to deposit uniform precursor.
