- Phase Relationship and Activities of Components in CaO-SiO<sub>2</sub>-Cr<sub>2</sub>O<sub>3</sub> Ternary System at 1573 K
抄録
<p>The knowledge of Cr2O3 activity in slag is necessary to decarburize chromium-containing special steel while minimizing the oxidation loss of chromium. In the present study, firstly, the phase relationship in the CaO-SiO2-Cr2O3 system was determined at 1573 K. Subsequently, the Cr2O3 activities in two- and three-phase coexisting slags at 1573 K were measured by equilibrating molten copper with oxide phases under a stream of Ar + H2 + CO2 gas mixtures, and the Gibbs energy changes of the formations of CaCr2O4 and Ca3Cr2Si3O12 were derived. It was found that the present results were compatible with the phase diagram and the literature data reported at higher temperature than 1573 K.</p>
