石墨类材料的性质相当大的程度上依赖于填料焦炭的性质。本文介绍国内几种典型石油焦和试验性焦炭的结构和性质,证明焦炭的热膨胀、可石墨化度取决于其消光轮廓的形状和大小,并决定着石墨的特性。文中还讨论了热处理的影响。
The nature of graphite-based materials depends to a large extent on the nature of the filler coke. This paper introduces the structure and properties of several typical petroleum coke and experimental coke in China. It shows that the thermal expansion and the degree of graphitization of coke depend on the shape and size of its extinction profile and determine the characteristics of graphite. The article also discusses the impact of heat treatment.
