High-temperature relative enthalpies of V2O5.
Albany, OR: U.S. Department of the Interior, Bureau of Mines, RI 9039, 1986 Jan; :1-7
Relative enthalpies of V2O5 from 298.15 to 1,101.0 K were measured at the Bureau of Mines to provide data needed for the advancement of mineral technology. Enthalpies were measured with a copper-block calorimeter. A sharp melting point was found at 951 K, with 15.690 kcal/mol for the standard enthalpy of melting. Tabulated values are given at selected temperature increments between 298.15 and 1,500 K for the standard relative enthalpy, heat capacity, entropy, and Gibbs energy function. Standard relative enthalpies are also given in equation form and combined with data from the literature to derive values of standard enthalpies of formation and Gibbs energies of formation.
