摘要：
The standard molar Gibbs free energy of formation of ZrOS has been determined in the temperature range 824-1246 K using a solid electrolyte galvanic cell of the type Pt|ZrOS, ZrO2|ZrO2(Y2O3)|Ni, NiO|Pt The measured e.m.f. could be represented by ( E mV) ± 1.5 = 1591.06 - 0.9251 T Using this equation and the reported standard molar Gibbs free energy of formation of Cu2S, NiO and ZrO2, the standard molar Gibbs free energy of formation of ZrOS was calculated and is given by ΔfG(ZrOS, s)/(J mol-1) ± 30 000 = - 689040 - 44.14 T log T + 103.88 T. © 1990.
