High-temperature relative enthalpies and related thermodynamic properties of Na2Ti6O13.
Albany, OR: U.S. Department of the Interior, Bureau of Mines, RI 9018, 1986 Jan; :1-6
Relative enthalpies of high-purity disodium hexatitanate (Na2Ti6O13) were measured at the Bureau of Mines to provide new thermodynamic data needed to advance the technology of materials. Measurements from 298.15 to 1,478 K were made by drop calorimetry with a copper block. Tabulated values are listed for the standard relative enthalpy, heat capacity, entropy, and Gibbs energy function between 298.15 and 1,500 K. Enthalpy data are also given in equation form and are combined with thermodynamic data from the literature to derive values of standard enthalpies of formation, Gibbs energies of formation, and logarithms of the equilibrium constants of formation. Similar calculations were made for the reaction of Na2O with TiO2.
