Preparation method and application of rare earth molybdate ceramic material synthesized by molten salt method
The invention relates to the technical field of new materials, in particular to a preparation method and application of a rare earth molybdate ceramic material synthesized through a molten salt method, the method comprises the steps that an RE source and a Mo source react in a molten salt system through the molten salt method, the rare earth molybdate ceramic material with the chemical formula being RExMoO (3x + 6)/2 is synthesized, RE is selected from one or more of La, Nd, Sm, Eu, Gd, Dy, Ho, Er and Yb, and x is larger than 0 and smaller than or equal to 6. The method has the advantages of low reaction temperature, simple process, short synthesis time, less impurity residual quantity, no pollution, low cost and the like, and can be used for synthesizing a luminescent rare earth ion doped rare earth molybdate material, and compared with pure rare earth molybdate, the luminescent property is further improved, and the luminescent effect is better. The material prepared by the method can be applied to environment-friendly dyes, ferroelectric materials, microwave ceramic materials, catalytic materials, luminescent materials or solid oxide fuel cells.
