Abstract

The results of a study of the properties of VPG-grade reactor graphite based on calcined pitch coke currently used as an alternative to KNPS-grade petroleum coke are reported. Technologies for production of new high-density fine-grained graphites based on calcined pitch coke and uncalcined pitch and resin cokes have been developed. Different shaping techniques — extrusion and hot pressing — have been tested. The newly developed high-density fine-grained graphites display superior physicomechanical properties and can be used for service in modified high-capacity reactors.
