壓電陶瓷（Piezoelectric Ceramic）是一種具有壓電效應的功能陶瓷材料，能夠将機械能與電能相互轉換。這種特性源于材料内部非中心對稱的晶體結構，當受到機械應力時會産生電荷（正壓電效應），反之施加電場時會發生形變（逆壓電效應）。
材料組成與特性
壓電陶瓷通常由钛酸鋇（BaTiO₃）、锆钛酸鉛（PZT）等化合物構成。通過高溫燒結和極化處理，其内部的電疇會定向排列，從而增強壓電性能。例如，PZT陶瓷的壓電常數可達$d_{33}=500 text{pC/N}$，適用于高靈敏度傳感器。
核心應用領域
研究進展
近年研究聚焦于無鉛壓電陶瓷（如铌酸鉀鈉基材料），以減少傳統含鉛材料的環境毒性。例如，德國達姆施塔特大學團隊開發的(K,Na)NbO₃陶瓷，其壓電性能接近商用PZT（《自然材料》，2024年6月報告）。
“piezoelectric ceramic”（壓電陶瓷）是由壓電材料與陶瓷工藝結合而成的功能材料，具備将機械能與電能相互轉換的特性。以下從定義、原理、材料和應用四方面詳細解釋：
定義與組成
壓電陶瓷是一種通過高溫燒結工藝制成的無機非金屬材料，具有壓電效應（即機械應力作用下産生電荷，或施加電場時發生形變）。其主要成分包括钛酸鋇（BaTiO₃）和锆钛酸鉛（PbZrO₃-PbTiO₃）等，這類材料在極化處理後呈現顯著壓電性。
工作原理
壓電效應分為正壓電效應（機械能→電能）和逆壓電效應（電能→機械能）。例如，壓電陶瓷受壓力時表面産生電荷（正效應），而施加電壓時會伸縮形變（逆效應），這一特性使其成為能量轉換的核心元件。
典型應用領域
材料特性優勢
相比石英等天然壓電材料，壓電陶瓷可通過摻雜改性調節性能（如提高靈敏度或溫度穩定性），且成本低、易于加工成複雜形狀。
如需進一步了解具體型號或制備工藝，可參考材料科學相關文獻或專業數據庫。
