摘要：
The standard Gibbs energies of formation of CoMoO4 and Co2Mo3O8 have been redetermined in the temperature range from 1119 to 1273 K by measuring electromotive forces of galvanic cells having a solid oxide electrolyte. The results are as follows: Delta(f)G(o) (CoMoO4)/kJ.mol(-1) = -1011 + 0.3044(T/K) +/-2 Delta(f)G(o)(Co2Mo3O8)/kJ.mol(-1) = -2285 + 0.7000(T/K) +/-5 where the standard pressure is 1 bar (100 kPa).
