摘要:
A process for preparing carbon electrodes is presented. In particular, a process for preparing carbon electrodes including the steps of combining calcined coke, a liquid pitch binder and carbon fibers derived from mesophase pitch to form an electrodestock blend; extruding the electrodestock blend to form a green electrodestock; backing the green stock to form a carbonized electrodestock; and graphitizing the carbonized stock by maintaining the carbonized stock at a temperature of at least about 2500.degree. C. for no more than about 18 hours is presented. The electrodes prepared by the inventive process are also presented.
