Tellurium melt crystallization study by differential-ray radiation and thermal analysis method

Phase transformation and melt crystallization can be accompanied by the appearance of electric charges on crystallization front, acoustical (AE), electron (EE), electromagnetic (EME) emission, or characteristic emission in infrared (CEIR, /spl lambda/ = 2-5 /spl mu/m) and visual (0.5 /spl mu/m) range of spectrum. Here the differential-ray radiation and thermal analysis (DRRTA) set-up is described, and study of the tellurium melt crystallization is carried out with use of the DRRTA method.
