用氧化钙稳定的片状氧化锆固体电解质定氧测头测定了1600℃时Fe-Nb-O合金的热力学性质。试验中采用了下列氧浓差电池Mo|Cr+Cr_2O_3|ZrO2(4％CaO)|Fe-Nb-O|Mo,测得的热力学性质如下: 用X射线衍射法检定的反应产物为NbO_2(当Nb>0.4％)。
The thermodynamic properties of the Fe-Nb-O alloy at 1600 ℃ were measured by the fixed-oxide zirconia solid electrolyte with oxygen sensor. The following thermodynamic properties were determined using the following oxygen concentration cell, Mo | Cr + Cr 2 O 3 | ZrO 2 (4% CaO) | Fe-Nb-O | Mo. The reaction product determined by X-ray diffractometry was NbO 2 Nb> 0.4%).
