Elastic properties of NaxK1-xBr and Naxk1-xCl solid solutions

A pulsed ultrasonic method has been used to measure the speeds of longitudinal and transverse elastic waves along 100] and 110] in single crystals of Na_xK_1-xBr and Na_xK_1–xCl solid solutions in the range 20–180°C; the elastic constants c_ik have been determined. These values have been extrapolated to 0°K, while the bulk modulus and shear modulus have been calculated.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 76–81, January, 1973.
