ABSTRACT

Pellets prepared from mixtures of synthetic ilmenite and graphite were heated in argon at 1000 to 1100 °C and the rate of reduction was followed gravimetrically. No measurable reaction was obtained at 1000 °C but the rate was high at 1100 °C. An inflection in the reduction curve at about 2 pct weight loss at 1050 and 1100 °C was due to the difficulty in nucleating iron. The rate is increased significantly by the addition of ferric chloride which promotes the nucleation of iron. The addition of rutile decreases the rate of reduction and the addition of manganese stabilizes a pseudobrookite phase. More... »
