| Abstract: | Based on the analysis of specific heat capacity of different solid materials, the relationship between
specific heat capacity of solid materials and temperature is studied and the model is built. As the example of Mo,Al2O3,graphite,W,Si3N4 and SiC, the model on specific heat capacity with temperature has been verified. The results indicate that the relative deviation between calculated and standard data is not exceeding 2%. |
