A Short Review on Copper Calcium Titanate (CCTO) Electroceramic: Synthesis, Dielectric Properties, Film Deposition, and Sensing Application

摘要: Electroceramic calcium copper titanates (CaCu3Ti4O12, CCTO), with high dielectric permittivities (e) of approximately 105 and 104, respectively, for single crystal bulk materials, are produced a number well-established emerging applications such as resonator, capacitor, sensor. These take advantage the unique properties achieved through structure CCTO. This review comprehensively focuses on primary processing routes, effect impurity, permittivity, deposition technique used electroceramics along their chemical composition micro nanostructures. Emphasis is given to versatile basic approaches that allow one control microstructural features ultimately determine CCTO ceramic. Despite intensive research in this area, none studies available literature provides all possible relevant information about fabrication, structure, factors influencing its properties, immobilization, sensing applications.
