摘　　要：以埔酸钇和碳酸氢铵为原料，通过向碳酸氢铵溶液滴加埔酸钇溶液，制备出了前驱物经950℃煅烧后颗粒尺寸大小为40-60nm的Y2O3粉体。该粉体在添加一定量的添加剂后经真空热压和热等静压成功烧结出红外透过率达82％的Y2O3透明陶瓷。A process of preparing Y2O3 transparent ceramics is presented. The precursor was obtained by adding Y（NO3）3 solution to the solution of NH4HCO3. Calcined at 950℃, the precursor converted into Y2O3 with grain size ranging from 40-60nm. Transparent ceramics was achieved by vacuum HPing and HIPing the powder mixed with sintering aid. Its IR transmission reached 82%.
