Effect of Cr2O3 Content on Viscosity and Melting Characteristics of Glass Melt

Abstract

Abstract: In order to ensure the smooth pouring of liquid glass, and to provide basic technical parameters for the co-preparation of CaO-MgO-Al₂O₃-SiO₂-Cr₂O₃ architectural glass-ceramics by blast furnace slag and chromium iron alloy slag, FactSage7.1 thermodynamic software was used to draw the five-element phase diagram of CaO-MgO-Al₂O₃-SiO₂-Cr₂O₃ glass system, and the viscosity and melting characteristics of the base glass melt were investigated through experiments. The results show that in the phase diagram drawn by FactSage7.1, with the increase of Cr₂O₃ content, the liquid phase region of the phase diagram is shrinking, indicating that the further melting of glass is hindered. When the mass fraction of nucleating agent Cr₂O₃ increases from 0.85% to 2.05%, the viscosity of glass melt decreases gradually and the melting temperature increases gradually, and the melting temperature should be higher than 1 469 ℃ when the CaO-MgO-Al₂O₃-SiO₂-Cr₂O₃ base glass is prepared by melting method. The increase of Cr₂O₃ content will increase the melting temperature of the base glass, which is reflected in the continuous increase of softening temperature, hemisphere temperature and flow temperature of each group of samples. Therefore, the content of Cr₂O₃ in the raw material ratio of base glass should be reduced as much as possible.
