Abstract
As part of the Bureau of Mines effort to provide thermodynamic data for the advancement of mineral technology, the Gibbs energies of formation of mos2 (molybdenite) and ws2 (tungsten disulfied) were determined with high-temperature galvanic cells employing stabilized zro2 (zirconia) as the electrolyte. A third-law analysis of the present data yielded a standard enthalpy of formation ah deg. 298F of -67.36+/-0.60 Kcal/mole of mos2. Experimental entropy and enthalpy data are needed to extend the present Gibbs energy of formation data to wider temperature ranges and derive a standard enthalpy of formation of ws2
