Investigation of Thermal Properties of SiC Ceramics Containing Carbon Nanostructures by Photothermal Measurements

This work presents an analysis of the influence of graphene reinforcement on properties of silicon carbide composites. Samples were prepared by a spark plasma sintering method. The density and hardness were obtained in the preliminary experiments. The thermal diffusivity was determined by the continuous wave photothermal technique with detection based on infrared radiometry. The thermal diffusivity is in the range of (0.48 to 0.57) cm 2⋅ s −1 for samples prepared from granulated SiC and in the range of (0.56 to 0.71) cm 2⋅ s −1 for samples prepared from SiC powder. Thermal properties are correlated with the density of SiC ceramics. The thermal diffusivity of samples with a higher density is lower in comparison to samples with a lower density.
