The Effect of Niobium Doping on the Electrical Properties of 0.4(BiK)TiO₃-0.6BiFeO₃ Lead-Free Piezoelectric Ceramics.

Ceramics in the system (BiK)TiO₃-BiFeO₃ have good electromechanical properties and temperature stability. However, the high conductivity inherent in BiFeO₃-based ceramics complicates measurement of the ferroelectric properties. In the present work, doping with niobium (Nb) is carried out to reduce the conductivity of (BiK)TiO₃-BiFeO₃.
