Abstract
This study was conducted to examine catalytic graphitisation of the graphite foam using B4C as a catalyst. Graphite foams were prepared by the template method using polyurethane foam. Two kinds of graphite foam were achieved by using different carbon source, mesophase pitch and high-softing-point pitch. The results show that adding B4C created an increase of the graphitisation degree and thermal conductivity of the graphite foam. For the graphite foam achieved from mesophase pitch, graphitisation degree can be increased by 97% while the thermal conductivity can be increased by 52·5%. For the graphite foam achieved from high-softing-point pitch, graphitisation degree can be increased by 227% while the thermal conductivity can be increased by 202%.
