Using the differential thermal analysis we investigated parameters of melting and crystallization processes of the CdTe based phase in CdTe-Al system near the CdTe side (CdTe + 2 mol. % Al, CdTe + 4 mol. % Al and CdTe + 6 mol. % Al). Varying temperatures of the melts intermediate isothermal holding for 10-, 30- and 60 minutes during their heating up to 1423 K we determined conditions of the melts full homogenization. It was concluded about change of the CdTe phase melting mechanism with Al content rise.
We detailed, by differential thermal analysis (DTA), some features of the melting- and cooling-processes in
CdTe-ZnTe with a ZnTe content of up to 10 mol. % by evaluating their influence on the parameters of melting and
crystallization. We focused on the heating/cooling rate, the melt's maximum temperature, and the duration of holding the
melt at this maximum. Using the interrelationship in the Kissinger equation, ln(V h/(TLmp)2) = A+ Ea/(R TLmp), between
the heating rate (V h) and the maximal temperature of the melting process's endothermic effect ( TLmp ), we estimated the
melting process's activation energy (Ea). In addition, we studied the temperature dependencies of the volume fraction of
the solid phase that remained in the CdTe-ZnTe melts, and the influence of the melt's "thermal prehistory" on the
parameters of its crystallization parameters. Due to these studies we assessed the temperature intervals of the solid
phases' existence and the temperature intervals of melts' crystallization.
