摘　　要：为了更好地对高品质环保重火石玻璃产品质量进行控制,使其满足高清光学系统对材料高透过性能的需求,通过生产过程对比,对环保重火石玻璃配比中唯一变化组分Nb 2O 5原料的晶形、粒度、微量杂质种类及含量进行分析,讨论了Nb 2O 5原料影响该系统玻璃的着色机制。结果发现,Nb 2O 5原料中微量元素Sb 2O 3的含量是影响玻璃透过性能的主要因素。因此,对该系统玻璃原材料中的总Sb 2O 3含量进行控制可以提高产品透过性能,稳定生产。To control the product quality of environmentally friendly heavy flint glass effectively,meet the requirements for high transmittance of high-definition optical system,we analyzed the crystalline forms,particle sizes,types and content of trace impurities of raw material Nb 2O 5 through comparing manufacturing processes.Nb 2O 5 was the unique changed component in environmentally friendly heavy flint glass.We discussed the coloring mechanism of raw material Nb 2O 5 to this type glass,and discovered that trace impurity Sb 2O 3 content in raw material Nb 2O 5 was the principle factor on glass transmittance.Therefore,controlling the total Sb 2O 3 content in this type glass can improve product transmittance and stabilize production.
