Dielectric, Piezoelectric and Ferroelectric Properties of (1-x)K_0.5Na_0.5NbO₃–xBiGaO₃ Lead-Free Ceramics

Abstract:

(1-X)K0.5Na0.5NbO3–xBiGaO3[(1-X)KNN-Xbg] Lead-Free Ceramics with Different Additive of Bigao3 Were Synthesized by Conventional Solid-State Sintering Technique. Dielectric, Piezoelectric and Ferroelectric Properties of (1-X)KNN-Xbg Lead-Free Ceramics Were Studied. it Is Found that the Piezoelectric Properties Was Improved due to the Additive Bigao3，The Ceramics X=0.01 near Room Temperature Exhibit Excellent Electrical Properties D33=152pC/N, TC=372 °C. these Results Indicate that Bigao3 Adjusted K0.5Na0.5NbO3-Based Ceramics Materials Are Promising Lead-Free Piezoelectric Ceramic Candidates for Practical Applications.
