Title: Tg studies on the reactions of hematite, magnetite and wüstite with COC12 and CO+Cl2
Abstract: The chlorination of hematite, magnetite and wüstite with COCl2 and CO+Cl2 were studied by thermogravimetry and X-ray diffraction. The equilibrium compositions of the gas- and solid-phases were determined by computer assisted thermodynamic calculations. During the chlorination of wüstite, as an intermediate product, FeCl2(s) was detected. A simulteneous transformation of wüstite was observed first into magnetite, and at higher temperatures, into hematite. In the case of the chlorination of magnetite with COCl2, hematite and FeCl2(s) were formed as intermediate products. The reaction of wüstite with CO+Cl2, started at very low temperatures and took place via the formation of FeCl2(s), FeCl3(s) and FeOCl(s).
