Method for preparation of pure phase Na1/2Bi1/2TiO3 ceramic powder
The invention provides a method for preparation of pure phase Na1/2Bi1/2TiO3 ceramic powder. The method includes: mixing Na2CO3, Bi2O3 and TiO2 evenly according to a mole ratio of 0.575:0.5:2 to obtain a mixture, then adding deionized water into the mixture, carrying out ball-milling, filtering and drying, then conducting heat preservation at 820-860DEG C, thus obtaining the pure phase Na1/2Bi1/2TiO3 ceramic powder. The method provided by the invention adopts solid phase synthesis of ceramic powder, and has the advantages of low cost, large output and simple preparation process, etc. With the characteristics of simple preparation process, simple operation and low cost, the method provides the foundation for large scale and low cost preparation of NBT ceramic powder.
