Method for preparing piezoelectric material fine grain powder
The invention discloses a method for preparing piezoelectric material fine grain powder. The method comprises the following steps: (1) for a piezoelectric material with a chemical formula of Pb (Zr0. 52Ti0. 48) O3, weighing PbO, ZrO2 and TiO2 which are subjected to drying treatment and accord with a stoichiometric ratio as raw material powder, weighing ball-milling beads which are 3-5 times of the total mass of the raw material powder and have a single diameter, and putting the ball-milling beads into a ball-milling device; (2) by taking deionized water or absolute ethyl alcohol as a ball-milling medium, ball-milling for 16-24 hours to uniformly mix the raw material powder; (3) carrying out drying treatment on the ball-milled slurry at 120 DEG C, putting into a crucible, sealing and pre-sintering to obtain Pb (Zr0. 52Ti0. 48) O3 single-phase powder; (4) putting the Pb (Zr0. 52Ti0. 48) O3 single-phase powder into a ball-milling device containing ball-milling beads, and carrying out secondary ball-milling treatment by taking deionized water or absolute ethyl alcohol as a ball-milling medium; and carrying out drying treatment on the slurry subjected to secondary ball milling at 120 DEG C to obtain Pb (Zr0. 52Ti0. 48) O3 fine grain powder with the average particle size of 80-110 nanometers. According to the method for preparing the piezoelectric material fine-grain powder, required equipment is simple, the process is simple and easy to implement, and the cost is low.
