Method for preparing carbon-graphite material through in-situ densification
The invention discloses a method for preparing a carbon-graphite material by in-situ densification, which comprises the following steps of: pressing and forming raw materials which contain volatile components and are used for preparing the carbon-graphite material to obtain a green body, then placing the green body in a closed container for roasting treatment, volatilizing the volatile components of the raw materials and increasing the internal pressure of the closed container to obtain the carbon-graphite material. And after roasting treatment is finished, obtaining the carbon-graphite material. According to the method for preparing the high-performance carbon-graphite material through in-situ densification, useless volatile components can be effectively reduced and can be partially converted into beneficial volatile components, and the prepared carbon-graphite material has high density and excellent mechanical properties.
本发明公开了一种原位增密制备炭石墨材料的方法，包括以下步骤：将含挥发分的用于制备炭石墨材料的原料压制成型得到生坯，然后再将生坯置于密闭容器中进行焙烧处理，使原料的挥发分挥发并使密闭容器内部压力升高，焙烧处理结束即得到炭石墨材料。本发明的原位增密制备高性能炭石墨材料的方法能有效减少无用挥发分并能够将其部分转化成有益挥发分，且制备的炭石墨材料具有较高的密度和优异的力学性能。
