2. Experimental Methods
Parallel-plate method
By inserting a material between two electrodes and measuring its capacitance, the dielectric constant is calculated from the measurement results. In the actual test setup, the two electrodes are mounted on a test fixture that clamps the dielectric sample. A source‑measure unit computes the dielectric constant, dielectric loss, impedance, and phase angle, and this data is then read in real time by proprietary software for plotting and recording, enabling dielectric measurements over a range of temperatures.
III. Experimental Procedure
Cutting-edge equipment: the art of temperature control with millimeter-level precision
In the laboratory area, a self-developed 1000°C temperature‑controlled dielectric test platform is achieving smooth transitions from room temperature to 1,000°C with a temperature control accuracy of ±0.1°C. This equipment combines a PID temperature‑control system with water‑cooling circulation technology, ensuring stable internal temperatures while employing electromagnetic shielding to isolate external interference. Paired with the Yokogawa IM3536 impedance analyzer’s wideband testing capability (4 Hz–8 MHz), it can simultaneously acquire dielectric response curves across ten frequency bands, effectively capturing the material’s electrical properties in high‑speed, dynamic detail.
Dielectric Thermal Spectroscopy System (DMS)
The testing process resembles a precision surgical procedure: platinum electrodes and ceramic samples are assembled with micrometer‑level alignment, while four probe sets act as tactile nerves, acquiring data in real time. As the temperature rises at a rate of 2°C per minute, the in‑house software simultaneously generates three‑dimensional ε‑T, D‑T, Z‑T, and θ‑T plots, revealing the material’s dielectric constant, loss factor, and phase angle as functions of frequency. The insulating‑property peak observed in the 300°C range provides critical parameters for the design of high‑temperature electronic devices.
