摘要
详细探讨了在制备(Bi1/2Na1/2)TiO3 BaTiO3(abbr.BNBT)系无铅压电陶瓷的过程中,合成条件Ty和烧结温度Ts对材料压电介电性能的影响,确定了较好的制备BNBT系压电陶瓷的工艺条件,并且系统地研究了(1-x)·(Bi1/2Na1/2)TiO3 xBaTiO3(x=0 02、0 04、0 06、0 08、0 10)的性能。XRD结构分析发现系统的相界在x=0 06,此时d33等压电介电性能参数达到最佳值。
The dependence of piezoelectric and dielectric properties of (1- x )(Bi_(1/2)Na_(1/2))TiO_3-xBaTiO_3 (abbr.as BNBT) on different calcining condition and different sintering temperature was researched. In order to determine the reasonable technological parameters, the influence of the preparing conditions was investigated. The piezoelectric and dielectric properties of (1- x )(Bi_(1/2)Na_(1/2))TiO_3- x BaTiO_3( x =0.02, 0.04, 0.06, 0.08, 0.10) non-lead-based ceramics system was studied. Accoring to XRD patterns, the morphotropic boundary lies in the composition of x =0.06, the main piezoelectric and dielectric properties of this system can reach the extreme values.
