摘要 对自蔓延高温合成金属钒的吉布斯自由能、单位热效应及绝热燃烧温度进行热力学计算和分析。结果表明,自蔓延高温合成金属钒能自发进行,且反应剧烈;绝热燃烧温度为3 021K,单位热效应为4 988J/g;高纯V2O5和铝粉的反应在943K左右发生,为液—固反应。 Gibbs free energy, thermal e{fect units and adiabatic combustion temperature of self-propagating high-temperature synthesis (SHS) vanadium were calculated and analyzed. The results show that thermodynamics of SHS vanadium is spontaneous and drastic. Adiabatic combustion temperature is 3 021 K. Thermal effect units is 4 988 J/g. The liquid-solid reaction of V2 05 and aluminum powder occurs at the temperature of about 943 K.
