Electrical Resistivity of Iron Phosphate Melts
AC electrical resistivity of iron phosphate melts, some of which contained simulated high level waste (HLW), was measured at temperatures from 950 to 1450°C. The redox ratio of iron ions in the glass was measured by Mössbauer spectroscopy. Electrical resistivity decreased slightly with time. In melts of low Na2O content the temperature dependent electrical resistivity was irreversible during the heating and cooling cycle. This irreversibility decreased with increasing Na2O content and was correlated to the iron redox ratio.
