Thermodynamic Properties of Three Sodium Titanates.

PB223879

Publication Date	1973
Personal Author	Bennington, K. O.; Brown, R. R.
Page Count	18
Abstract	Enthalpies of formation of three sodium titanates were determined by hydrofluoric acid solution calorimetry. The values obtained for formation from the elements at 298.15 deg K are minus 370.9 plus or minus 0.5 kcal per mole, for Na2TiO3, minus 832.1 plus or minus 0.9 kcal per mole for Na2Ti3O7, and minus 1,510.9 plus or minus 1.7 kcal per mole for Na2Ti6O13. Tables of enthalpies of formation and Gibbs energies of formation are given as a function of temperature both from the elements and from the component oxides for Na2TiO3 and Na2Ti3O7. (Author)
