Thermodynamic properties were determined by the Bureau of Mines for the intermetallic compound tial3. Heat capacities were obtained from 5 to 303 k by adiabatic calorimetry. The derived value of s298.15 is 22.08+/-0.07 Cal/deg-mole. Enthalpies relative to 298 k were obtained from 298 to 1,413 k by copper-block drop calorimetry. No anomalous thermal behavior was noted in the temperature ranges investigated. Low- and high-temperature data were combined with a known enthalpy of formation at 298 k to give values of enthalpy of formation and Gibbs energy formation, 0 to 1,400 k.
