Manufacturing method of graphite material having high thermal expansion coefficient and graphite material thereof

摘要

Problem to be solved: to provide a method of producing a graphite material having a high thermal expansion coefficient using a conventional artificial graphite raw material without using natural graphite as a raw material.Solution: a method of manufacturing a graphite material having a high thermal expansion coefficient in which a carbon material fired at 80.degree. C. to 1200.degree. C. is heated to 2400.degree. C. to 300.degree. C. to be subjected to a compressive load during the process of graphitization.Diagram
