Low Temperature Sintering of (Ba_0.98Ca_0.02)(Sn_0.04Ti_0.96)O₃ Ceramics Using CuO-B₂O₃ as a Sintering Additive

Abstract:

The effects of CuO-B₂O₃ (CBO) additive on densification, microstructure, and electrical properties of (Ba_0.98Ca_0.02)(Sn_0.04Ti_0.96)O₃(BCST) cermaics were investigated. The phase compositions, microstructure, dielectric, ferroelectric and piezoelectric properties of BCST ceramics were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), precision impedance analyzer, ferroelectric tester and quasi-static piezoelectric constant testing meter, respectively. The results show that CuO-B₂O₃(CBO) frit can improve the densification and promote low-temperature sintering of BCST ceramics prepared by a conventional solid-state reaction method. Dense BCST ceramics with CBO can be sintered at temperatures as low as 1175 °C, which is approximately 275 °C less than the sintering temperature of pure BCST. When sintered at 1200 °C, the optimized properties of the BCST ceramics with 0.5 wt% CBO were obtain as ε = 1206, d₃₃ = 346 pC/N, k_P = 0.39, tgδ = 0.009.
