In this paper, the influence of basicity (CaO/SiO₂) on the viscosity and crystallization characteristics of chromium-containing high-titanium slag was studied. The melting temperature and viscosity were measured by employing the hemisphere and rotating cylinder methods, and the composition and morphology of the crystallized phase were analyzed by X-ray diffraction and scanning electron microscopy-energy dispersive spectroscopy. The results showed that the crystallization sequence during the cooling process was spinel, followed by anosovite. The increased basicity led to enhanced softening, hemispherical, and flowing temperatures of chromium-containing high-titanium slag; however, the viscosity significantly decreased. The basicity obviously affected the crystallized phase composition. Furthermore, anosovite was the dominant crystallized phase and a proper level of basicity was beneficial for titanium enrichment.

本文中，碱度的影响（CaO / SiO ₂）对含铬高钛渣的粘度和结晶特性进行了研究。通过半球法和旋转圆筒法测定熔融温度和粘度，并通过X射线衍射和扫描电子显微镜-能量色散光谱法分析结晶相的组成和形态。结果表明，冷却过程中的结晶顺序是尖晶石，然后是凹凸棒石。碱度提高导致含铬高钛渣的软化，半球形和流动温度提高；但是，粘度显着降低。碱度显然影响结晶相的组成。此外，
