【摘要】 本文在作者原有工作的基础上,进一步研究了MoO₃和Cr₂O₃对CaO-Al₂O₃-SiO₂系玻璃的晶化和显微结构的影响。结果表明;MoO₃和Cr₂O₃都能促使该类玻璃的整体晶化;它们作为晶核剂的合适用量相应为MoO₃ 2～4wt%,Cr₂O₃ 1～1.75wt%。本文还对其晶化的机理和显微结构进行了讨论,为该系统玻璃的微晶化和进一步开发新材料提供新的实验结果。更多还原

【Abstract】 Based on the authors’ previous research work, the effect of MoO₃ and Cr₂O₃ on the crystallization and microstructure of CaO-Al₂O₃-SiO₂ system glass is further studied. The result shows that both MoO₃ and Cr₂O₃ can promote bulk crystallization of the glass. As a nucleating agent, we suggest its suitable content as follows: MoO₃ 2～4 wt%, Cr₂O₃ 1 ～l.75 wt%. In this paper, the mechanism of crystallization is also discussed. This work provides new results for further developing a new kind of material and microcrystallization of the glass in this system.更多还原
