Abstract:The basic principles of highly purification for the aphanitic graphite are briefly discussed in this article. According to the characteristics of raw materials,an improved combined pyro-hydro technology is selected for purification of the aphanitic graphite,and the optimal technological parameters are determined. Research results show that the improved pyro-hydro purifying method can increase fixed carbon content of the aphanitic graphite from 84.18% to 99.25%.
Keywords:Aphanitic graphite  High purity  Roasting  Acid pickling
