Abstract
Heat capacities of sulfate, perrhenate, chloride, and iodide sodalites with the ideal
formula Na8Al6Si6O24X2 (X = SO4, ReO4, Cl, I) were measured from 2 K to 300 K using a
Quantum Design Physical Property Measurement System (PPMS). From the heat capacity data,
the standard thermodynamic functions were determined. All four sodalites undergo a phase
transition below room temperature for which thermodynamic parameters were determined.
Additionally, the heat capacity of one of the constituent compounds (NaReO4) was measured.
