An investigation was made of the effect of hydrostatic pressures upon the interdiffusion of KBr/KCl couples. The application of a hydrostatic pressure which was of the order of 10 to 100kg/cm2 inhibited the development of porosity, and the Frenkel effect did not occur. The results of marker experiments revealed increasing marker movement with increasing pressure. At 660C, under a pressure of 1atm., the rate of movement was 2.2 x 10-10cm/s. At 660C, under a pressure of 50atm., the rate of movement was 3.9 x 10-9cm/s.
