  • Abstract
    General ageing reasons, inherent to all piezoelectric resonators, fall into the following groups: subsurface, structural and contact ones. High-Q and high-stability quartz crystal units have irreversible frequency variation with time due to structural reasons only. Long-term frequency instability due to ageing of precision quartz crystal oscillators constitutes the value of 1-2×10-12 per day, which agrees well with theoretical results at temperatures of the order of 310 K
