In order to investigate the main factors affecting the service life of graphite anodes used in preparation of rare earth metals, a range of analytical tools, including a digital microscope, an optical microscope, an SEM, XRD, a simultaneous thermal analyzer and a four-probe tester were employed for comparison and comprehensive evaluation of macroscopic and microscopic morphology, crystal structure, graphitization, thermal properties and resistances of graphite anodes with different service lives. The results indicate that the resistance, internal cracks and porosity of graphite anodes contribute mainly to the difference in the service life of graphite anodes. The research results can be of reference for selection of graphite anode in preparation of rare earth metals, thus providing technical assistance for enterprises to realize cost reduction and efficiency improvement.
