:Lu2O3 transparent ceramics were fabricated successfully by vacuum sintering along with hot isostatic pressing (HIP) post-treatment from the nanopowders. The influences of calcination temperature on morphology and microstructures of powders and ceramics were studied systematically. The optimal ceramic sample from the nanopowders calcined at 1050°C shows uniform and dense microstructure with the in-line transmittance of 81.5% at 1100 nm. The results of the thermal measurements, i.e. thermal conductivity and specific heat, were related to the ch...
