Abstract

Abstract: 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℃.

Key words: BaTiO₃, conductivity, NaOH-KOH eutectic salt
