The production process of graphite sintering crucible for lithium industry was studied. These processes include the use of high graphitized needle coke as a filler, vibration molding using a starting coke mixture, medium temperature coal tar pitch impregnation combustion cycle, combustion of shaped compounds in a metal vessel, and graphitization of combustion materials in a graphite cylinder. The latter two techniques of graphite sintering crucible for lithium Industry reduce the temperature drop of bulk raw materials during heat treatment, thereby minimizing cracks caused by reduced thermal stress. All of the recommended technologies can be implemented in existing electrode plants, which can greatly improve the quality of the produced bismuth graphite. In this case, the quality of the resulting material can meet world standards.
