Abstract	We report paratellurite's 300-10-K elastic constants C ij, six constants reflecting tetragonal symmetry (P422 point group). The quantity e 14 2/k 11, where e 14 denotes the sole independent piezoelectric constant and k 11 denotes a dielectric constant, was determined over the same temperature range. All the principal C ij show approximately regular temperature-change behavior: increasing with decreasing temperature, the increases being 2%-10%. One derived elastic constant, C′=(C 11-C 12)/2, a shear constant, shows strongly anomalous temperature behavior, decreasing continuously during cooling to 10 K, the total decrease being 5%. The quantity e 14 2/k 11 was essentially independent of temperature. Obtained by resonant-ultrasound spectroscopy, our results differ from previous studies, none of which went to 10 K, a temperature region of much practical interest for this material. From the near-zero-temperature elastic constants, we derive a Debye temperature of 235 K. The slope dC′/dT yields a negative Gruneisen parameter γ=-0.9, close to the specific-heat value. © 2004 American Institute of Physics.
