常圧ソルボサーマル法による均質な MgAl₂O₄ の調製

抄録

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.
