【摘要】 制备了不同掺钛量的钛掺杂石墨并研究了其导热性能。结果表明,与相同条件制备的纯石墨材料相比,钛掺杂石墨的导热性能大大提高。微观结构分析表明,材料的石墨化程度大大提高,同时,材料的石墨化程度与其导热性能间呈现出较为复杂的关系。钛组元最终以碳化钛形式存在于炭基体中,并直接影响着材料整体的导热系数。更多还原

【Abstract】 Titanium doped graphites were prepared and their microstructure were studied. Results showed that titaniumdoped graphite have higher thermal conductivity compared with pure graphite, which was made by same technology.Microstructure analysis showed that graphitization degree of Ti-doped graphite increased and the correlation betweengraphitization degree and dopant quantity is complex.At last,titanium was in the form of titanium carbide in thematerials, and they affected the thermal conductivity of the material directly.更多还原
