In this article, we have reported a novel approach to fabricate translucent alumina ceramics induced by doping additives via chemical precipitation. For this approach, alumina powder was first mixed with metal nitrates and dispersed by PEG-2000 as dispersant, and then the pH value was tailored by introducing the NH3∙H2O into the suspension to favor the precipitation of Mg2+ and Y3+ onto the Al2O3 matrix. It is found that the dopants are smaller and more homogeneously dispersed via chemical precipitation in the translucent alumina sample as compared with conventional ball milling. Furthermore, it is believed that the approach of chemical precipitation followed by H2 sintering at high temperature within short sintering time could make a good balance between the real in-line transmission and the cost.
