Method for synthesizing Dy2TiO5 powder by molten-salt growth method
The invention relates to a method for synthesizing Dy2TiO5 powder by a molten-salt growth method. The method comprises the following steps: (1) uniformly mixing dysprosium oxide, titanium oxide and alkali metal salt by a ball mill to obtain mixed powder; (2) drying the mixed powder obtained in the step (1) for 6-10h; (3) grinding the material dried in the step (2) and carrying out pre-press forming; (4) warming the material pre-press formed in the step (3) to 800-1400DEG C and preserving the heat to calcine for 1-4h; (5) grinding the material calcined in the step (4), washing by deionized water, filtering, and drying the solid to obtain the Dy2TiO5 powder. According to the preparation method, the Dy2TiO5 powder is synthesized through the molten-salt growth method; compared with a sol-gel process, the preparation method is free of gel process, simple in process, rapid in synthesis speed and low in production cost; the prepared powder is small in grain, uniform in size, good in dispersibility and free of grain adhesion and reunion phenomena.
