Lead-free Ba0.85Ca0.15Zr0.1Ti0.9O3 ferroelectric ceramics with refined microstructure and high strain under electric field by mechanosynthesis

Lead-free ferroelectric Ba0.85Ca0.15Zr0.1Ti0.9O3 stands out among environmentally friendly alternatives to commercial Pb(Zr,Ti)O3 piezoceramics for its large piezoelectric coefficients, and it is especially suitable for applications in which thermal depoling is not an issue like bio-implanted device...
