Abstract
An electrochemical method for the in situ purification of heavy metal fluoride melts has been developed. Several factors which influence the efficiency of purification such as electrode materials, rotation rate , temperature, deposition time and purification times have been studie d. The purified glasses were analyzed using graphite furnace atomic ab sorption spectroscopy (GFAAS). The results show that Fe, Cu and Ni imp urities in fluoride glass melts can be reduced to the level of 0.3-0.5 ppm.
