研究目的
To study the influence of various additives on the structure and ferroelectric properties of NBT-BT-BMT ceramics.
研究成果
The study confirmed that KCl additives improved the dielectric and piezoelectric parameters of the NBT-BT-BMT ceramics, while V2O5 additives led to a decrease in these parameters. A linear correlation between piezoelectric coefficient d33 and dielectric permittivity ert values at room temperature was observed.
研究不足
The study focused on a specific composition and set of additives, which may limit the generalizability of the findings to other systems or conditions.
1：Experimental Design and Method Selection:
The study involved the preparation of ceramic samples by the solid state reaction method, with the addition of various additives (Bi2O3, KCl, LiF, V2O5) to the base composition. The samples were then sintered at different temperatures.
2：Sample Selection and Data Sources:
Starting materials included carbonates and oxides of specified purity grades.
3：List of Experimental Equipment and Materials:
X-ray diffraction (DRON-3M, CuKa-beam), Scanning Electron Microscopy (JEOL YSM-7401F with a JEOL JED-2300 energy dispersive X-ray spectrometer system), dielectric spectroscopy (Agilent 4284 A), and Atomic Force Microscope system MFP-3D SA (Asylum Research, USA) were used.
4：Experimental Procedures and Operational Workflow:
The samples were prepared, sintered, and then analyzed for their crystal structure, microstructure, dielectric properties, and piezoelectric behavior.
5：Data Analysis Methods:
The data were analyzed to determine the effects of additives on the properties of the ceramics.
