Hypothesis
The study investigates how the content and temperature of C@TiC affect the dielectric properties and microwave absorption performance of C@TiC/SiO2 composites.
Conclusion
The study found that increasing the C@TiC content enhances the microwave absorption performance, with the 30 wt.% C@TiC composite showing the strongest absorption capabilities.
Supporting Evidence
- The composite with 30 wt.% C@TiC shows a minimum reflection loss of -55.87 dB at room temperature.
- The 50 wt.% C@TiC composite maintains a reflection loss below -10 dB from room temperature to 400 °C.
- Increasing C@TiC content improves both dielectric properties and microwave absorption performance.
Takeaway
This study shows that adding more C@TiC to a material helps it absorb microwaves better, especially at high temperatures.
Methodology
C@TiC/SiO2 composites were fabricated using blending, cold-pressing, and sintering methods, and their properties were evaluated at various temperatures.
Limitations
The study does not address the long-term stability and durability of the composites under extended high-temperature and high-frequency microwave exposure.
