Preparation and Microwave Absorption Properties of T i 3 A l C 2 Synthesized by Pressureless Sintering T i C / T i/ A l
Source abstract
Abstract
The T i 3 A l C 2 powders were synthesized by pressureless sintering method at 1250–1400°C. It was found the powders synthesized at 1350°C had a higher purity. Dielectric and microwave absorption properties of the T i 3 A l C 2 powders were investigated in the frequency range from 8.2 to 12.4 GHz. The complex permittivity of the T i 3 A l C 2 /paraffin decreased with increasing calcining temperature and decreasing T i 3 A l C 2 content. The minimum reflection loss of the T i 3 A l C 2 /paraffin shifted to the lower‐frequency region by increasing the thickness. For the single‐layer T i 3 A l C 2 /paraffin mixture with 70 wt% T i 3 A l C 2 content, the reflection loss values exceeding −10 dB were achieved when the thickness is 2.8 mm.
