In the course of investigations on the kinetics of sulfation of natural dolomite, CaMg(CO/sub 3/)/sub 2/, as the sorbent for SO/sub 2/, it has been found that Mg ions can be made to sulfate, leading to the formation of a double salt, Mg/sub 3/Ca(SO/s

Cesium diuranate (Cs2U2O7): heat capacity (5 to 350 K) and thermodynamic functions to 350 K. A re-evaluation of the standard enthalpy of formation and the thermodynamics of (cesium + uranium + oxygen)

Autor: Henry R. Hoekstra, Howard E. Flotow, P.A.G. O'Hare

Publikováno v: The Journal of Chemical Thermodynamics. 13:1075-1080

The low-temperature (5 to 350 K) heat capacity of a well-characterized sample of β-Cs2U2O7 has been measured by adiabatic calorimetry. No anomalies were observed in the plot of heat capacity against temperature, the curve having the normal sigmoid s
