用交流阻抗谱法测量了３５０℃时共晶成分的ＮａＯＨ－ＫＯＨ熔盐中加入ＴｉＯ２和ＢａＣＯ3时体系电导率的变化,准确给出了３５０℃共晶成分ＮａＯＨ－ＫＯＨ熔盐的电导率为１．０５３Ω－１·ｃｍ－１,确认了在ＮａＯＨ－ＫＯＨ熔盐中ＴｉＯ２与ＢａＣＯ３反应,生成ＢａＴｉＯ３时熔盐不参与反应．实验数据表明３５０℃ＴｉＯ２与ＢａＣＯ３在共晶成分的ＮａＯＨ－ＫＯＨ熔盐中的溶解过程可在短时间内达到平衡．
The conductivities of eutectic NaOH-KOH molten salt during the process of forming BaTiO3 from BaCO3 and TiO2 were measured by A.C. impedance method at 350℃. Results showed that the accurate conductivity of eutectic NaOH-KOH molten salt at 350℃ was 1.053Ω-1· cm-1. The dissolution of BaCO3 and TiO2 in NaOH-KOH of eutectic component at 350℃ reached equilibrium in a short time, and NaOH and KOH did not react with BaCO3 and TiO2 at 350℃.
