Method for preparing BNT-based leadless piezoelectric ceramic powders

DU JINGHONG / ZHOU PING

The invention discloses a method for preparing BNT-based leadless piezoelectric ceramic powders and belongs to the technical field of inorganic powder materials. According to the technical scheme of the invention, metal salts are adopted as raw materials. A complexing agent and water are added in the raw materials to prepare a mixed solution. Then a monomer, an initiator and a catalyst are added to prepare a polymer network gel. The polymer network gel is subjected to microwave drying and calcining to obtain BNT powders. The method is simple in preparation process, convenient in operation and low in cost. prepared BNT ((Bi0.5Na0.5)TiO3) powders are small in particle size, high in specific surface area, uniform in particle size distribution and accurate in stoichiometric ratio.
