摘要:
The vat photopolymerization (VPP) technology offers exceptional flexibility in design and manufaction of high-performance piezoceramic structures. However, due to the high refractive index and strong UV absorption characteristics of Pb-based ceramics, ceramic slurries are required to have a low solid content in for efficient deep-curing. This limitation often results in sintering distortion, cracking, low density, and deteriorated piezoelectric properties. To address these challenges, a heat treatment process was initially employed to spheroidize the PZT powder, which effectively decreased lig...
