THE EFFECT OF PRESSURE IN BINDERS ON IMPROVED JOINING STRENGTH OF ISOTROPIC BULK GRAPHITE

摘要

Isotropic bulk graphite is used in various industries as heating elements,crucibles,and electrodes.Generally,bulk graphite is obtained through a set of processes:powder mixing,shaping,carbonization,impregnation,re-carbonization,and graphitization.Bulk graphite is difficult to fabricate into large shapes,and produces a high amount of scrap material'·2.To resolve these issues,some researchers have developed methods of joining small volumes of bulk graphite3.However,the joining characteristics of bulk graphite have not been extensively studied.This study examined the effect of pressure in binders on the joining strength of bulk graphite.
