The effects of different kinds of nucleating agents on crystallization, microstructure and performances of Magnesium Aluminosilicate (MgO-Al₂O₃-SiO₂, MAS) glass-ceramics which were fabricated by melting method in this study. Also, this paper systematically investigated the mechanism of glass stability, crystallization kinetics and element distribution of MAS glass-ceramics. Herein, we used three kinds of nucleating agents, which was TiO₂, ZrO₂ and composite nucleating agent (TiO₂/ZrO₂). The results showed after the doping of nucleating agent, the content of α-cordierite was increased, the stability and crystallization kinetics of glass was changed, the precipitated crystal phase was finer and more compact. Wherein, the sample with composite nucleating agents (TiO₂, ZrO₂) has the best performance due to the highest contents of α - cordierite, uniform distribution of elements without agglomeration in the crystal phase and the most compact structure, whose Vickers hardness and bending strength can reach 9.70 GPa and 312 MPa, respectively.

研究了不同种类成核剂对熔融法制备的镁铝硅酸盐(MgO-Al ₂ O ₃ -SiO ₂ , MAS)微晶玻璃的结晶、微观结构和性能的影响。此外，本文系统地研究了MAS微晶玻璃的玻璃稳定性、结晶动力学和元素分布的机理。在这里，我们使用了三种成核剂，即 TiO ₂、ZrO ₂和复合成核剂（TiO ₂ /ZrO ₂）。结果表明，掺杂成核剂后，α-堇青石含量增加，玻璃的稳定性和结晶动力学发生变化，析出的晶相更细密致密。其中，含有复合成核剂（TiO ₂、ZrO ₂）的样品由于α-堇青石含量最高，晶相中元素分布均匀，无团聚，结构最致密，维氏硬度和弯曲性能最好。强度可分别达到 9.70 GPa 和 312 MPa。
