In this paper, the effect of adding molde of stearic acid on the injection molding process were studied, the modification mechanism of stearic acid to alumina powder as well as the influence of the performance of the feeding and injection were discussed. In addition, the defects of being easy to the introduction in injection molding products were sum- marized. The results showed that the surface of the alumina powder was firstly modified by stearic acid to reduce the aggre- gates and the compatibility, dispersibility, the uniformity of feedstock and injection property were improved by this process. The density and three-bending strength of the sintered samples were improved.
