压电陶瓷（Piezoelectric Ceramic）是一种具有压电效应的功能陶瓷材料，能够将机械能与电能相互转换。这种特性源于材料内部非中心对称的晶体结构，当受到机械应力时会产生电荷（正压电效应），反之施加电场时会发生形变（逆压电效应）。
材料组成与特性
压电陶瓷通常由钛酸钡（BaTiO₃）、锆钛酸铅（PZT）等化合物构成。通过高温烧结和极化处理，其内部的电畴会定向排列，从而增强压电性能。例如，PZT陶瓷的压电常数可达$d_{33}=500 text{pC/N}$，适用于高灵敏度传感器。
核心应用领域
研究进展
近年研究聚焦于无铅压电陶瓷（如铌酸钾钠基材料），以减少传统含铅材料的环境毒性。例如，德国达姆施塔特大学团队开发的(K,Na)NbO₃陶瓷，其压电性能接近商用PZT（《自然材料》，2024年6月报告）。
“piezoelectric ceramic”（压电陶瓷）是由压电材料与陶瓷工艺结合而成的功能材料，具备将机械能与电能相互转换的特性。以下从定义、原理、材料和应用四方面详细解释：
定义与组成
压电陶瓷是一种通过高温烧结工艺制成的无机非金属材料，具有压电效应（即机械应力作用下产生电荷，或施加电场时发生形变）。其主要成分包括钛酸钡（BaTiO₃）和锆钛酸铅（PbZrO₃-PbTiO₃）等，这类材料在极化处理后呈现显著压电性。
工作原理
压电效应分为正压电效应（机械能→电能）和逆压电效应（电能→机械能）。例如，压电陶瓷受压力时表面产生电荷（正效应），而施加电压时会伸缩形变（逆效应），这一特性使其成为能量转换的核心元件。
典型应用领域
材料特性优势
相比石英等天然压电材料，压电陶瓷可通过掺杂改性调节性能（如提高灵敏度或温度稳定性），且成本低、易于加工成复杂形状。
