Reliable quadric for frequency-turnover temperature vs. orientationof rotated Y-cut quartz plate resonator oscillating in the thirdovertone C-mode in the vicinity of AT-cut

摘要

This paper describes the reliable quadric for third overtonefrequency-turnover temperature vs. orientation of cut for rotated Y-cutquartz crystal plate in the vicinity of AT-cut in the temperature range-196~250° C. From the present relation we can show the usefulpiezoelectric cuts of quartz for the resonator and sensor at theelevated temperature region. In particular, the experiments are carriedout in the vicinity of AT-cut
