The thermal diffusivity and conductivity of a silicon carbide fiber-reinforced lithium aluminosilie glass-ceramic was measured using the laser-flash method. As indied by the effect of specimen thickness on thermal conductivity and its positive temperature dependence, heat transfer by radiation makes a significant contribution to the total thermal conductivity.
Because of high thermal conductivity, dimensional stability and extremely high hardness, silicon carbide (SiC) arouses much interest in researchers [12 15]. In order to reach the desired thermal conductivity of polymer composites, thermal conductive networks should be established.
20/9/2018· Silicon nitride usually offers comparatively low thermal conductivity compared to silicon carbide or aluminium nitride owing to its unique chemical composition and crystal structure. These fine ceramic grains typically grow faster in a lengthwise plane, resulting in an interlocking needle-like structure that exhibits anisotropic thermal properties.
