High-purity MgAl_2O_4 spinel powders were prepared from heterogeneous alkoxide solution with fine MgO powders. In present study, effects of HCl added in preparing spinel precursors ware examined. A little addition of HCl was found to make forming temperature of spinel decreased and to enhance the sinterability remarkably. Sintering temperature of 1400℃ was enough to produce dense polycrystalline spinel and some of polycrystals were transparent.
