Abstract

The Ti₃AlC₂ powders were synthesized by pressureless sintering method at 1250-1400C. It was found the powders synthesized at 1350C had a higher purity. Dielectric and microwave absorption properties of the Ti₃AlC₂ powders were investigated in the frequency range from 8.2 to 12.4 GHz. The complex permittivity of the Ti₃AlC₂/paraffin decreased with increasing calcining temperature and decreasing Ti₃AlC₂ content. The minimum reflection loss of the Ti₃AlC₂/paraffin shifted to the lower-frequency region by increasing the thickness. For the single-layer Ti₃AlC₂/paraffin mixture with 70 wt% Ti₃AlC₂ content, the reflection loss values exceeding -10 dB were achieved when the thickness is 2.8 mm.
