Lithium Niobate: A High‐Temperature Piezoelectric Transducer Material
暂无分享,去创建一个
The high piezoelectric coupling and high Curie point of LiNbO3 make it an excellent transducer material for acoustic measurements at high temperatures. A single‐crystal plate of LiNbO3 has been used as a shear mode transducer in measuring the acoustic properties of an Al2O3 ceramic sphere up to 1050°C.
