Integral heats of mixing have been measured at 738 K by drop calorimetry. Liquidus and solidus temperaturesT 9 and recrystallisation temperatures have been measured by thermal analysis.
Thermodynamical data on Sb-Te system at 909,30 K, 911,85 K and 917,95 K. The integral molar enthalpies of formation of liquid Sb-Te alloys were measured at three temperatures by drop calorimetry.
The heat capacities of Bi.4Te. 6 in the solid and liquid states are calculated from the results of the experimental “drop calorimetric” method, and the heat of fusion of the compound is deduced.
Acquisition et traitement de donnees microcalorimetriques
Application a la mise en œuvre d'un microcalorimetre Tian-Calvet −1000°C
This paper describes a Basic language program for use with an APPLE II microcomputer on line in a microcalorimetric set. Automatic area measurements, permanent control of physical parameters of manipulations and calculations lead to enthalpy values defined with an accuracy better than one per cent.
