Abstract: A molten
oxide reactor that uses induction heating has been designed to quickly heat slag to a
superheated liquid for rapid molten oxide electrolysis experiments. The reactor can heat
slag containing 10% Fe3O4 to 250 °C above its melting point of 1400 °C in 10
minutes and sustain the molten slag at 1650 °C for more than an hour in an argon
environment. Molten slag can be held in ... read morethermal equilibrium with molten nickel which
allows for the development of an electrode for electrochemical experiments. More than 10
grams of slag can be heated using a 15 kW Lepel induction heating power supply while
consuming approximately 1.07 kW at steady state. A graphite susceptor transferred heat
generated by induction to 2.7 times more slag using 74% less power than a nickel
susceptor. The graphite susceptor provided evenly distributed heating because of its
cylindrical geometry. Thermal FEA supports the experimental
findings.
