摘　　要：为稳定地生产出高品质的环保重火石玻璃产品,满足高清光学系统对材料品质的需求,通过对SiO_2-TiO_2-Nb_2O_5体系环保重火石玻璃的配方及制造工艺因素进行试验与分析,从玻璃结构层面讨论了该系统玻璃在不同制备条件下的着色机制,发现玻璃中Pt^(4+)的质量分数、熔制气氛、玻璃组分的氧化还原性均会对玻璃颜色和光谱性能造成影响。To produce the high quality environmentally-friendly dense flint glass and meet the requiremcal system to materials, the experiment and analysis on the composition and manufacturing process factors of SiO 2 -T iO 2-Nb2 05heavy flint glass were carried out Also, the coloring mechanism of this glass at different preparation conditions was discussed with structure analysis. tt is found that glass color and spectral property were affected by Pt4＋content, the melting atmosphere, and oxidation-reduction quality of glass components.
