Conclusions

  1. 1.

    Ruthenium carbide exists at high temperatures (2000–2250°K).

  2. 2.

    The dissociation energy of the ruthenium carbide molecule is 149±5 kcal/mole.

  3. 3.

    The heat for the sublimation of ruthenium and ruthenium carbide from the ruthenium-carbon system is respectively −155±2 and −175±2 kcal/mole.
