研究目的
To investigate the phase transition, microstructure, and electrical properties of (1-x)(K0.495Na0.495La0.01)(Nb0.997Cu0.0075)O3-xBi(Mg0.5Zr0.5)O3 ceramics for high-temperature capacitor applications.
研究成果
The KNLNC-xBMZ lead-free ceramics exhibit high dielectric permittivity and low dielectric loss over a wide temperature range, making them suitable for high-temperature capacitor applications. The KNLNC-0.02BMZ ceramic, in particular, shows promising properties with high dielectric permittivity and small variation in dielectric permittivity from 100 to 375 (cid:2)C.
研究不足
The study focuses on the dielectric properties and microstructure of KNLNC-xBMZ ceramics, but the mechanical properties and long-term stability under high-temperature conditions are not addressed.
1：Experimental Design and Method Selection:
The ceramics were prepared by the conventional solid-state method.
2：Sample Selection and Data Sources:
High purity raw materials were used.
3：List of Experimental Equipment and Materials:
X-ray diffractometer (XRD, D/MAX-2500, Rigaku), scanning electron microscopy (SEM, JSM-6360, JEOL), LCR meter (HP 4980, Agilent), and piezo-d33 meter (ZJ-3A, Institute of Acoustics Academic Sinica).
4：Experimental Procedures and Operational Workflow:
The powders were mixed, ball milled, calcined, re-milled, pressed into disks, sintered, and then coated with silver paste for electrical measurements.
5：Data Analysis Methods:
The phase structures were identified by XRD, microstructures were studied by SEM, and dielectric properties were tested by an LCR meter.
