Abstract

We investigated melting and crystallization processes of Cd_0.50Mn_0.50Te. Using differential thermal analysis (DTA) we studied the solid-liquid equilibrium temperature range, the temperature dependence of the volume fraction of the solid phase in the melt, and crystallization peculiarities. We observed that changing a dwell temperature from 1346 to 1354 K results in an increase of the crystallization temperature of the Cd_0.50Mn_0.50Te melt. Since the melt is in a semiliquid state, its crystallization occurs over a solid-phase domain. It was found that a slightly overheated Cd_0.50Mn_0.50Te melt (up to 10 K) crystallizes more slowly than more overheated melts, and that the Cd_0.50Mn_0.50Te solid solutions are in a semi-liquid state in the temperature range of 1338-1354 K.
