The invention provides a preparation method of magnesium niobate, which comprises the following steps: carrying out wet ball milling on MgO and Nb2O5, uniformly mixing, and drying to obtain mixed powder; the mixed powder is heated to 1500-1700 DEG C for 1-3 h and then subjected to water quenching, and solid particles of a core-shell structure inclusion are obtained; and heating the solid particles to 1000-1200 DEG C, and carrying out heat preservation to obtain the magnesium niobate. Solid particles of a core-shell structure inclusion are formed through a water quenching process, then MN obtained through rapid heating sintering is high in purity and stability, Mg < 2 + > and Nb < 5 + > in the MN are high in uniformity and large in reaction activity, sufficient mixing with PbO and TiO2 at a high temperature is facilitated to form a liquid phase, the formed raw material for PMNT crystal growth is better in singleness and uniformity, and the preparation method is simple and easy to implement. Furthermore, the PMNT single crystal with a single perovskite structure, high purity and excellent piezoelectric property can be obtained, and the yield is improved.

The invention provides a polymer composite solid electrolyte membrane preparation method, which comprises: 1, dispersing a polymer substrate in an organic solvent according to a mass ratio of the polymer substrate to the organic solvent of 0.05-0.8; 2, dispersing the HNTs particles in an organic solvent according to the mass ratio of the functional agent HNTs to the organic solvent being 0.01-0.1; 3, dispersing the additive particles in the organic solvent according to the mass ratio of the additive to the organic solvent being 0.01-0.1; 4, respectively pouring the HNTs and the additive turbid liquid into the solution obtained in the step 1; and 5, pouring the electrolyte slurry into a polytetrafluoroethylene mold to obtain a polymer composite solid electrolyte layer, and putting the polymer composite solid electrolyte layer into a hot press for hot pressing to obtain the final solid electrolyte membrane. The invention also provides the polymer composite solid electrolyte membrane which is formed by using the preparation method. The conductivity of the polymer solid electrolyte is improved, and the mechanical strength and the interface stability after film formation are improved.
