以乙二胺为溶剂，采用溶剂热法制备了镥铝石榴石纳米粉体。我们发现反应介质、反应温度和保温时间是影响LuAG纳米粉体合成的重要因素。得到了最佳的制备条件。合成的LuAG纳米粉体为单相，具有分散性好、无团聚、球形晶粒细、粒径分布较窄等优良性能，在陶瓷的压实和烧结方面具有广阔的应用前景。该溶剂热合成路线为低温制备LuAG纳米粉体提供了新的途径。
Lutetium aluminum garnet (LuAG) nanopowders were successfully synthesized by a solvothermal method using ethylenediamine as a solvent. We found that the reaction medium, the reaction temperature and the holding time are important factors during the synthesis of LuAG nanopowders. Optimum preparation conditions were obtained in this work. The synthesized LuAG nanopowders are single-phase with desirable properties such as good dispersivity, no aggregation, fine spherical grains and a relatively narrow grain size distribution suggesting that the LuAG nanopowders are promising for application in the compacting and sintering of ceramics. This solvothermal synthesis route provides a new approach for the preparation of LuAG nanopowders at low temperatures.
