Description:
This invention belongs to the field of piezoelectric ceramic material research and specifically relates to a PZT-5A porous piezoelectric ceramic material, its preparation method, and applications. The material is composed of the following raw materials: PZT-5A powder, nano carbon black, a dispersant, and an organic carrier.
The mass ratio of PZT-5A powder to nano carbon black is 228:(9–11), and the dispersant accounts for 1% to 2.5% of the combined mass of the PZT-5A powder and nano carbon black.
This invention provides a method for preparing a PZT-5A porous piezoelectric ceramic using nano carbon black as a sacrificial template. The resulting material exhibits a uniform porous structure with a porosity of approximately 25% and pore sizes ranging from 1 µm to 5 µm. It is suitable for various applications, including ultrasonic sensing, broadband piezoelectric transducers, and energy harvesting.
