Abstract

Abstract The effects of SiO2 and CO2 on the crystallization action of Ti-containing mixed molten slag (molten Ti-containing blast furnace slag and molten Ti slag) were discussed by thermodynamic calculation and specific experiments. The results of thermodynamic calculation indicated that the increase of SiO2 addition mass and CO2 oxidation time can promote the transformation of anosovite and sphene to rutile. The experiment results showed that the phase composition of modification slag was only rutile under the SiO2 addition mass of 110 g and the CO2 oxidation time of 180 s. Moreover, the formation theory of rutile was investigated. Using CO2 as an oxidizing gas can not only prepare rutile but also achieve carbon neutrality, which is a clean preparation method.
