Electrical and mechanical properties of bismuth sodium potassium titanate doped with a modified barium titanate lead-free ceramics
© 2019, © 2019 Taylor & Francis Group, LLC. Piezoelectric ceramics of bismuth sodium potassium titanate doped with a modified barium titanate (BNKT-xBTNb, x = 0.00–0.06) were prepared via the solid-state reaction process. The effect of BTNb on the phase formation, mechanical, dielectric, ferro...
