Abstract

The elastic, piezoelectric and dielectric constants of single crystals of Sr_0.5Ba_0.5Nb₂O₆ have been measured in the temperature range 0-35 degrees C, using a combination of ultrasonic pulse echo, piezoelectric resonance and capacitance techniques. The material shows strong bulk wave coupling (k₃₃=0.53) and certain shear coefficients (¹/₂(C₁₁^E-c₁₂ ^E), c₄^E and c₆₆^E) show anomalous temperature behaviour. The SAW properties of the singly rotated substrate orientations have been calculated. The maximum surface wave coupling factor predicted is 0.023 and a number of predicted temperature compensated orientations have been located. The results of the SAW measurements made are in agreement and temperature compensation has been demonstrated on a (110) cut, (001) propagating substrate. Interesting observations on the piezoelectrically stiffened elastic constants in unpoled material are discussed in terms of a domain wall model.
