Fabrication of transparent nanoceramics is attracting more and more interests recently. In this study a new method of amorphous sintering followed by controlled crystallization (ASCC) was developed, and transparent LaAlO3/t-ZrO2nanoceramic was prepared as an example. Based on a eutectic composition of Al2O3–La2O3–ZrO2, glass powders were synthesized, sintered, and then converted to nanoceramics by post-heat-treatment. The heat-treatment performed at 1200°C for 2h produced a transparent LaAlO3/t-ZrO2nanoceramic with an average grain size of 40nm. Due to the nanoscale microstructure, the ceramic showed a transparency up to 55% at 800nm (1mm thick), Vickers hardness of 19.05GPa, and fracture toughness of 2.64MPam1/2, respectively.
