    The electrical conductivity of melter type slags
    (2003) Hundermark, Rodney; Jahanshahi, Sharif; Sun, Shouyi
    This thesis details an investigation into the factors affecting the electrical conductivity of slags containing some or all of the following components: Ah03, cae, Cr203, FeOx, MgO and Si02. The interest in the electrical properties of these slags originated from problems being experienced in the electrical control of the melter type furnaces of the platinum producers in South Africa. A large amount of literature on the electrical conductivity of slags was collected and analysed. The key research areas identified through the literature review were: the effect of iron oxide on slag conductivity in terms of ionic and electronic mechanisms, the effect of oxidation state on the conductivity of iron-containing slags and the effect of chromium on the electrical conductivity of melter type slags. Measurements of the electrical conductivities of various slags were conducted in order to gain an understanding of these effects.
