Process for producing carbon product having coarse and dense structure |
摘要 |
A process for producing a carbon product having coarse and dense portions, the process including producing an integral porous carbon having high strength and uniform porosity distribution with dense structure carbon moldings. The carbon moldings are produced by calcining in an inert gas atmosphere a composite of (a) a green molding, a precarbonized material or a carbide and (b) chlorinated vinyl chloride resin particles, the chlorinated vinyl chloride resin producing, when carbonized in an inert gas atmosphere, a coarse structure. Dense carbon is formed by carbonizing the green molding, precarbonized material or carbide. Thus, the carbon product has coarse and dense portions.
