Slags produced after reduction smelting of Bayan Obo niobium concentrate were taken for research, and laws of influence for basicity on slag viscosity, turning point temperature and viscous-flow activation energy were explored by testing viscosity characteristics of high-temperature smelting slags. Samples taken at the turning point temperature and as the viscosity reaching 8 Pa·s were quenched respectively, and then taken for observing crystalline phases. It is found that the basicity of the slags exerts a significant effect on its high-temperature viscosity characteristics. An increase in temperature leads to a decrease in viscosity, while as basicity increases, the viscosity initially decreases and then increases. Specifically, at a basicity of 1.0, the viscosity attains the minimum value of 0.2 Pa·s at 1 500 ℃; while at 2.0, the viscosity increases remarkably. Both the turning point temperature and viscous flow activation energy at a basicity of 1.0 reach their minimum values, 1 325 ℃ and 243.61 kJ/mol. At different basicity, slags initially have different crystalline phases. At a basicity of 0.5, calcium silicate is the main precipitated phase; at 1.0, perovskite and titanite are precipitated; while at 1.5 and 2.0, perovskite is the dominant precipitated phase.

以白云鄂博铌精矿还原熔炼渣系为研究对象，通过高温熔渣的黏性特征测试，考察了碱度对熔渣黏度、转折点温度和黏流活化能的影响规律；分别在转折点温度以及黏度8 Pa·s时取样淬冷，观察了结晶物相。结果表明，渣系碱度显著影响其高温黏性特征。黏度随温度升高而降低，随着碱度增加先下降后上升，其中碱度1.0时，1 500 ℃下黏度为0.2 Pa·s；碱度2.0时黏度显著增加。转折点温度和黏流活化能在碱度1.0时达到最低值，分别为1 325 ℃和243.61 kJ/mol。在不同碱度下，渣系的初始结晶相不同，碱度0.5时主要析出了硅酸钙，而碱度1.0时析出了钙钛矿和榍石，碱度1.5和2.0时主要析出了钙钛矿。
