摘要
采用β（β″）-Al2O3固体电解质管组装固体电解质电池Pt｜Sb2O5,NaSbO3‖β（β″）-Al2O3‖NaCrO2,Cr2O3｜Pt和Pt｜TeO2,Na2TeO3‖β（β″）-Al2O3‖NaCrO2,Cr2O3｜Pt。测量不同温度下达到平衡时的电池反应电动势,计算NaSbO3和Na2TeO3生成自由能,建立生成自由能与温度的关系。得到在700~1300K范围内NaSbO3生成自由能与温度的关系为：ΔGθNaSbO3=-655.88＋0.2039T±4.10（kJ/mol）;在700~1100K范围内Na2TeO3生成自由能与温度的关系为ΔGθNa2TeO3=-700.35＋0.0519T±9.29（kJ/mol）。
The solid electrolyte cells Ptl Sb2O5, NaSbO3 β 13 （ β＂）-A1203 II NaCrO2, Cr2O3 I Pt and Pt I TeO2, Na2TeO3 II 13 （β＂）-A12 O3 II NaCrO2, Cr2 O31Pt were assembled using △ （β＂）-A12O3 as solid electrolyte, and the for- mation free energies of NaSbO3 and Na2TeO3 were calculated by measuring the electromotive force （EMF） of cells. The relationship between formation free energy and temperature （700 - 1300 K） for NaSbO3 can be described as △GN,shO3 = -655.88 ＋0. 2039T ＋4. 10 （kJ/mol） and that for Na2TeO3 in the temperature range of 700 ~ 1100 K can be described as △GNO2TeO3 = -700.35 ＋0. 0519T ＋9.29 （kJ/mol）.
