Co:MgAl2O4 nanopowders were synthesized via reverse-strike co-precipitation, and highly transparent Co:MgAl2O4 ceramics were fabricated via vacuum sintering and HIP post-treatment. The influence of the amount of ammonium carbonate addition on the properties of the as-synthesized precursor, nanopowders and ceramics were investigated. The result shows that the volume of ammonium carbonate has an impact on the dispersity of Co:MgAl2O4 nanopowders and the optical quality of ceramics. The agglomeration of Co:MgAl2O4 nanopowders is affected due to the final pH value, and the nanopowders obtained at 0.5 L ammonium carbonate appear less agglomeration. The optimum optical quality of final Co:MgAl2O4 transparent ceramics with 0.5 L ammonium carbonate can be obtained, having a high in-line transmittance of 84.4% at 400 nm and 86.9% at 1 100 nm, as well as the average grain size of 21.3 μm.
