Then, TiC x -paraffin composites with stable performance were obtained through the infiltration process. Based on this, the morphological structure, thermal conductivity, and high-temperature stability were tested. The results indicated that the initial stoichiometric ratio of Ti to C had a significant influence on the skeleton structure and high temperature stability. As the x value increased from 0.5 to 1, the porosity of the skeleton rose from 31.7% to 51.8%. When subjected to a high temperature of 100°C for 10 hours, the loss rates of TiC 0.5 -paraffin, TiC 0.7 -paraffin, TiC 0.9 -paraffin, and TiC- paraffin composites are 19.5%, 20.2%, 21.1%, and 24.2% respectively. A lower stoichiometric number is more conducive to the stability of the composites.
