摘要Percent BaTiO3：羟基磷灰石（HAp）复合材料已显示出在合成骨材料中可能应用的前景。本文报道了钙钛矿家族钛酸钙与羟基磷灰石复合材料的合成和电性能，钛酸钙是一种众所周知的铁弹性材料，在低于50 K的温度下显示出量子顺电样的介电行为。研究了这些复合材料的介电和热释电性能。结果表明，CaTi 〇 3在具有HAp的复合材料中保持其特征行为，因此其量子顺电类行为得以维持。结果进行了讨论，在量子顺电或初期铁电行为的标准巴雷特方程。
ABSTRACT Perovskite BaTi03: hydroxyapatite (HAp) composites have shown promises for possible applications in synthetic bone materials. This paper reports the synthesis and electrical properties of composites of the perovskite family calcium titanate, a well known ferroelastic material that shows quantum paraelectric-like dielectric behavior at temperatures below 50K, with hydroxyapatite. The dielectric and pyroelectric properties of these composites have been studied. The results show that CaTi03 retains its characteristic behavior in the composite with HAp and thus its quantum paraelectric-like behavior is sustained. Results are discussed in view of the standard Barrett equation for the quantum paraelectric or incipient ferroelectric behavior.
