INVESTIGATION OF MASS TRANSFER IN THE COMPLEX SYSTEM Te-Tl BY THE CONTACT-MELTING METHOD
A. A. Akhkubekov and B. S. Karamurzov UDC 553.23:621.315.592 An investigation of the kinetics of contact melting of the complex system Te-Tl under unsteady diffusion conditions is made. The growth of the contact interlayer obeys a parabolic law. The interdiffusion coefficient is calculated in the temperature range 260-300oC. It has been found that virtually does not change within the temperature range 260-280oC. The effect of decrease in the temperature of contact melting relative to the equilibrium eutectic is established. A relationship between the superheating of a melt of the stable eutectic and the magnitude of its supercooling is found. Kabardino-Balkar State University, Nal'chik, Russia.
