Description
Suchanicz leads a team studying manganese- and iron-doped ceramics in a 2024 paper. The base material is a sodium bismuth titanate ceramic. The team measured stiffness, hardness, toughness, and bending strength in unpoled and poled states, a first for this material.
Adding iron or manganese improved mechanical traits, as did electric poling. The additives also improved piezoelectric behavior. Stress-strain tests showed doping lowered the stress needed to switch domains and raised leftover strain. Poling had the opposite effect. The materials showed large deformation and strong leftover polarization under high stress. The authors suggest they could replace lead-based ceramics in actuators that need high blocking stress.
