Thermodynamic data for the ruthenium oxide RuO₂(s) are basic data for the calculation of gaseous release in the case of severe nuclear accident. The present study is a critical analysis of thermochemical data for RuO₂(s) based on available published experimental data from calorimetry, vapor pressures in equilibrium with the diphasic RuRuO₂ and Electromotive Force Measurements EMF. A full critical review and reinterpretation of data are presented in this work with a proposition of new and accurate data for RuO₂(s): C°p (RuO2, s, 298.15 K) = 56.42 ± 0.08 J·K-1 ·mol-1, S°298.15 (RuO2,s) = 46.15 ± 0.05 J·K-1 ·mol-1, and Δ; fH298 (RuO2,s) = −312.3 ± 1.6 kJ.mol-1,

氧化钌RuO ₂（s）的热力学数据是计算严重核事故时气体释放的基本数据。本研究是对RuO ₂（s）的热化学数据的批判性分析，其依据是来自量热法，与两相Ru RuO ₂平衡的蒸气压和电动势测量EMF的可用已公开实验数据。本文提出了对RuO ₂（s）的新的准确数据的建议，对数据进行了全面的批判性审查和重新解释：C°p（RuO2，s，298.15 K）= 56.42±0.08 J·K-1·mol -1，S°298.15（RuO 2，s）＝ 46.15±0.05J·K-1·mol-1，Δ。fH298（RuO2，s）= −312.3±1.6 kJ.mol-1，
