Thermal Conductivity of Fine-grain Doped Graphite at Elevated Temperatures

Abstract

Abstract: Fine-grain doped graphites, which possess excellent thermal-mechanical properties, were prepared by the ball-milling dispersion method. At the same time, the correlation between microstructure observed by SEM, EDX and XRD and the properties of the doped graphite was discussed. Such materials had dense and homogeneous structure with carbides dispersed uniformly in the carbon substrate, and showed an excellent thermal conductivity at elevated temperatures and thermal shock resistance.

Key words: doped graphite, microstructure, thermal conductivity, thermal shock resistance
