The electrical conductivity of natural and synthetic slags (containing 14 to 36 wt% Fe) was measured from 1200 to 1700 K at O 2 pressures from 1 to 2×10 −6 atm. The conductivity is relatively high (∼10 −2 Ω −1 cm −1 at 1700 K) and stems from the transfer of electrons between Fe 2+ and Fe 3+ ions. Anomalies in the conductivity around 1600 K are the result of devitrification of the glass samples.
