Static Frequency-Temperature Characteristics of Doubly Rotated Quartz.

Abstract

The static frequency characteristics of crystallographically doubly rotated quartz as a function of temperature, f(T), are described. Curves showing the sensitivity of the normalized frequency offset to small misorientations in angle are developed. Three different sets of currently accepted temperature coefficients of elastic constants are applied to calculate f(T). We show that for specific orientations of practical interest, the three sets predict significant differences in the inflection and turnover temperatures. The crystallographic orientations showing this angular sensitivity are the ones to be exploited experimentally to establish the regions in which the different sets are valid. Detailed computations are performed for orientations yielding 80 C turnover temperatures and for the SC-cut. (Author)
