Effect Of Li2co3 Addition On The Piezoelectric And Dielectric Properties Of Pb0.93la0.02sr0.05(Zr0.52ti0.48)O3 Ceramics

Lead zirconate titanate (PZT) is the most widely investigated amongst lead-based perovskite ceramics. Its piezoelectric and dielectric properties are always modified with different dopants. When PZT doped with La3+ and Sr2+, the piezoelectric constant (d33) and dielectric constant (εr) are increase...
