Abstract
A pulsed ultrasonic method has been used to measure the temperature dependences of the elastic moduli, the constants Cik and Sik, the anisotropy factors, the bulk moduli, and the Poisson ratios over the temperature range 300-120 ° K for NaCl and over the range 300-80 ° K for KCl. The Debye temperatures of these compounds are calculated from the elastic constants extrapolated to 0 ° K.
