Low-temperature Heat Capacities and High-temperature Enthalpies of Chiolite (Na5al3f14),.
MISSING :8 pages
Low-temperature heat capacities of chiolite (na5al3f14) were determined by adiabatic calorimetry in the temperature range 5.8 To 300 k. The derived standard entropy (s deg., 298.15) Was 115.6 +/_ 0.2 Cal/deg-mole. High temperature enthalpies relative to 298.15 K were obtained by precision drop calorimetry up to 1,000 k. Tables of experimental data and related thermodynamic functions are given for the temperature range of experimental observations.
