Piezoceramic materials generally exhibit a notable instability of their functional properties when they work under real external conditions. This undesirable effect, known as nonlinear behavior, is mostly associated with the extrinsic contribution to material response. In this article, the role of the ferroelectric domain walls' motion in the nonlinear response in the most workable lead-based a...

In present study, the polymerization depths for implementation of laser stereolithography process in system (oligomer - piezoceramics) on wavelengths 445-465 nm UV range were determined original BTO, KNN and NBT lead-free piezoceramic pastes. It was shown that powder pastes, which provide a depth more than 150 μm, are promising using 3D printing. Such chosen to guarantee sufficient overlap neig...
