Abstract：The effect of the toxic substances of carbon/carbon composites by different graphitization treatment times and their impact on osteoblast growth was studied. The results show that prolonging heat treatment can remove toxic substances As and Pb, and reduce Hg, Cd, Al, and other toxic contents. In addition, osteoblasts slowly grow by short time(4,8h) high-temperature treatment and show an obvious toxic effect, but osteoblasts grow well on the carbon/carbon composite surface by long time(12,16h) high-temperature treatment.Thus, extended heat treatment can significantly improve the biocompatibility of the carbon/carbon composites.
