The invention relates to a preparation method of Y 0.5 Gd 0.5 TaO 4 nano-powder, and relates to the technical field of refractory materials. dissolving into an alcohol solution in a manner to obtain a clear solution; adding an appropriate amount of polymerization accelerator to the obtained clear solution, mixing uniformly, and drying in an oven at 45-70 °C to obtain the Y 0.5 Gd 0.5 TaO 4 nanopowder precursor; Y 0.5 Gd 0.5 TaO 4 nano-powder can be obtained from the precursor obtained by high temperature calcination. The preparation method has the advantages of simple process, low equipment requirements, far lower synthesis temperature than the commonly used high-temperature solid-phase reaction method, and the obtained Y 0.5 Gd 0.5 TaO 4 nano-powder has good crystallization and high purity. |
