Abstract:

Liquidus temperatures in the system FeO–Fe₂O₃–SiO₂–TiO₂ at five oxygen pressures in the range 2 × 10⁻² to 10⁻⁶ atmospheres have been measured for the iron oxide rich corner of the system. These data are presented on diagrams using %SiO₂, %TiO₂ and %(FeO; Fe₂O₃) to express the concentrations. Iso %Fe₂O₃/ %FeO ratio lines for 1500°C are given on the diagrams. The effect of SiO₂ and TiO₂ on the Fe³⁺ /Fe²⁺ ratio in the melts at 1500°C is discussed and the effect of TiO₂ additions on the ratio is shown to be less than that of SiO₂.
