Fine ceramics (advanced ceramics, advanced technical ceramics). Characteristic of piezoelectric properties under high-load conditions - Resonant-antiresonant method under high-temperature conditions1 Scope This document specifies a method of measuring piezoelectric properties of piezoelectric fine ceramics and other piezoelectric devices under high temperature conditions, where the electromechanical coupling coefficient is determined based on measurements of resonance antiresonance frequencies using impedance analysers.
