Temperature coefficients of crystalline-quartz elastic constants over the cryogenic range [4  K, 15 K]

This paper brings out the temperature coefficients of synthetic-quartzelastic constants atliquid helium temperature. The method is based on the relationship between theresonance frequencies of aquartz acoustic cavity and theelastic constants of the material. The temperature coefficients of theelastic constants are extracted from experimental frequency-temperature data collected within the very usefulcryogenic range [4  K–15 K] from a set ofresonators of various cut angles, because of theanisotropy ofquartz.
