Electrically active bioglass has received much attention as artificial bone graft material. In this study, the dielectric and piezoelectric properties of calcium phosphate-barium zirconium titanate bioglass-ceramics (CPGs-BZT bioglass-ceramics) were investigated as a function of BZT content. The BaZr 10, 20, 30, 40, 50 wt.%) was prepared by an incorporation method. Crystallization temperature of each glass was measured by differential thermal analysis (DTA). XRD and SEM techniques were also used to characterize the phase formation and microstructure. The results showed that the BZT content caused an increase in dielectric and piezoelectric properties. The bioactivity of BZT/CPGs bioglass-ceramics was found to be higher than that of the pure CPGs after soaking in SBF for 14 days.

Lead-free ceramic powders based on Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) were successfully fabricated by the conventional solid-state reaction method. Two kinds of sintering methods: zero-time sintering (ZTS) and conventional sintering (CS) were applied to obtain BCZT ceramics. The microstructure and dielectric properties of BCZT ceramics sintered from the ZTS and the CS method were systematically studied. It was found that the coarse-grained samples with grain sizes ~ 19-21 μm were obtained from the ZTS and the CS method. The CS method with a long time of dwelling was helpful for improving the dielectric properties of lead-free BCZT ceramics. The maximum dielectric constant of 9926 and low dielectric loss of 0.0108 were obtained at CS with 8h.

Magnetoelectrically active multiferroics have been of a significant interest and have instigated intense research and development owing to their potential applications. [1][2][3][4][5] From the perspective of fundamental physics, 6-10 multiferroic properties are often grouped into two categories, that is, Type I, where a ferromagnetism and a ferroelectricity
