随着光学仪器的发展,不仅需要研制一系列新品种光学玻璃,而且对商品光学玻璃质量的要求也愈来愈高。要制得高质量的光学玻璃除采用新型的熔制工艺和设备外,对商品光学玻璃配方的改进也是提高商品光学玻璃质量的重要途径。BaK_7、BaK_8是属于钡冕类型含大量氧化钡的硼硅酸盐系统玻璃。过去,由于使用 With the development of optical instruments, not only need to develop a series of new varieties of optical glass, but also the quality of optical glass products are also getting higher and higher requirements. To obtain high-quality optical glass In addition to the use of new melting process and equipment, the improvement of commercial optical glass formulations is also an important way to improve the quality of commercial optical glass. BaK_7, BaK_8 belong to the barium corona type borosilicate glass containing a large amount of barium oxide. In the past, due to use
