Extrusion of graphitic bodies

摘要

A method of forming graphitic bodies comprises the steps of:- a) forming under high shear a mouldable composition comprising:- i) graphite powder; ii) a binder; and iii) a fluid carrier b) working under high shear said mouldable composition to form an extruded shape; c) forming bodies from said shape; and d) heat treating said bodies to stabilise the structure. In which either the fluid carrier is an aqueous fluid carrier, and/or the bodies are impregnated to close porosity and/or the bodies are machined to form structures in their surface.
