Abstract

The investigations of vanadium vaporization from CaOSiO2FeOV2O5 thin film slags were conducted using the single hot thermocouple technique SHTT with air as the oxidizing atmosphere The slag samples were analyzed after the experiments by SEM/EDX The vanadium content was found to decrease as a function of time The loss of vanadium from the slag film after 30 minutes of oxidation was approximately 18 pct and after 50 minutes it was nearly 56 pct The possible mechanism of vanadium loss would be the surface oxidation of vanadium oxide in the slag VO x to V5+ followed by surface evaporation of V2O5 which has a high vapor pressure at the experimental temperatureThe authors are thankful to TUBergakademie Freiberg Germany for making the experimental facilities available Financial support to Ms Shyrokykh by the Ministry of Education Sports and Youth of Ukraine is gratefully acknowledged We thank the German Research Council for the award of the Mercator visiting professorship to Seshadri Seetharaman at TUBergakademie Freiberg Germany The financial support from the Division of Materials Process Science at the Royal institute of Technology Stockholm with respect to the materials costs is acknowledged The work has been carried out as part of the Swedish national project “Ecosteelmaking” financed by The Swedish Foundation for Strategic Environmental Research MISTRA through Jernkontoret
