Graphite blocks with high thermal conductivity derived from natural graphite …

Abstract. In this work, natural graphite flake (NG) and mesophase pitchwere used as precursor carbons to prepare the graphite blocks, which were dopedwith Si and Ti powders. After hot-pressed at 2700 C,weinvestigated the effect of mean size ofNGon properties and microstructure of the graphite blocks. Results showed that both thermal conductivity and flexural strength of the graphite block…
