This paper presents the effects of Li₂O addition on the non-isothermal melt crystallization of Cuspidine in CaO–SiO₂–CaF₂ glass. The addition of Li₂O retarded crystallization at all cooling rates and converted the mode of nucleation from instantaneous to progressive. Two types of kinetic analysis indicated anti-Arrhenius behavior in the samples, which means that overall crystallization was governed by nucleation. Furthermore, the change in effective activation energy indicated that the addition of Li₂O impeded the initial stage of crystal formation. Therefore, the addition of Li₂O retarded the crystallization of CaO–SiO₂–CaF₂ melt as a result of suppression of nucleation. These results increase our understanding of melt crystallization kinetics of glass for use as mold flux in continuous casting steel production.

本文介绍了Li ₂ O的添加对CaO–SiO ₂ –CaF ₂玻璃中Cuspidine的非等温熔融结晶的影响。Li ₂ O的添加在所有冷却速率下均会阻止结晶，并将成核模式从瞬时转变为渐进模式。两种动力学分析表明样品中的抗阿累尼乌斯行为，这意味着整体结晶受成核作用支配。此外，有效活化能的变化表明Li ₂ O的添加阻碍了晶体形成的初始阶段。因此，Li ₂ O的添加阻碍了CaO–SiO ₂ –CaF ₂的结晶。由于抑制成核作用而熔化。这些结果增加了我们对连续铸造钢生产中用作保护渣的玻璃熔体结晶动力学的理解。
