Abstract: Abstract To achieve high piezoelectricity and the corresponding good temperature stability of BaTiO3 (BT) ceramics, a new system of (1-x-y) BaTiO3 – yCaTiO3 – x(BaZr1-zHfz)O3 (BT-yCT-xBZHz) was designed. The O-T phase boundary was observed at 0.065 ≤ x ≤ 0.085, 0.08 ≤ y ≤ 0.12 and 0 ≤ z ≤ 1.0… read more here.

Abstract: Developing piezoelectric ceramics with high piezoelectric properties and broad temperature usage ranges via low-temperature sintering is one of decisive importance for flourishing developments for emerging electromechanical applications. However, these properties are usually mutually exclusive, such… read more here.
