Effect of Li2CO3 on structure and electrical properties of low-temperature-sintered 15PSN-52PMN-33PT ceramics
Li 2 CO 3 -doped 15PSN-52PMN-33PT (PSN-PMN-PT- x wt%Li 2 CO 3 ) piezoelectric ceramics were successfully synthesized at 1100 °C by the two-step columbite precursor method. Their microstructure, dielectric, ferroelectric, and piezoelectric properties were systematically investigated. The optimum comp...
