The variation of elastic constants of MgO with temperature has been measured from 4.2 to 300 K. The values of the elastic constants at 4.2 K, in units of 10 10 N/m 2 , are C 11 = 30.67, C 12 = 9.371 and C 44 = 15.76. This gives a limiting value of θ 0 = 948 K for the Debye characteristic temperature
