tailieunhanh - Structure, microstructure, and piezoelectric properties of knlns-bnkz lead-free ceramics under the effect of different sintering temperatures

The experimental results showed that with an increase of the TS temperature, the structure of the ceramics transformed from an orthorhombic-tetragonal mixed phase (O-T) at TS 1100 °C into a rhombohedral-tetragonal (R-T) mixed phase with a dense microstructure of uniform grain size at TS = 1110 °C. When TS was further increased. |
