Abstract The Bureau of Mines has measured the low-temperature heat capacities and high-temperature enthalpies of crystalline K2Si2O5 as part of a program for advancing mineral resources technology with energy economy. High-temperature enthalpies of glassy and liquid K2Si2O5 and crystalline K2SiO3 were also measured. Tabulated values of C(p) sup 0, S sup 0, -(G sup 0 -H(0) sup 0)/T, and H sup 0 -H(0) sup 0 from 5 to 300K are given for K2Si2O5. Also tabulated are delta H sup 0, delta K sup 0, and log K for formation of K2SiO3 and K2Si2O5 from both the elements and the oxides.
