摘要
研究了B2O3含量为20%(质量分数)时B2O3-La2O3-Ta2O5-ZrO2和B2O3-La2O3-Nb2O5-ZrO2系统的玻璃形成区域。在此基础上,逐一添加各种改善析晶性能的氧化物,研制出一种高折射率低色散的ZLaF4光学玻璃,并对其熔炼工艺、析晶性能作了一定的探讨,对一些性能进行了测试。
Glass formation region of B2O3-La2O3-Ta2O5-ZrO2 and B2O3-La2O3-Ta2O5-ZrO2 systems containing 20% B2O3 （in mass）has been determined. Other oxides which can improve divitrification characteristics of the glass were then added respectively. A new type of ZLaF4 optical glass with high refractive index and low dispersion has been developed. Its melting process and divitrification characteristics were also discussed and its some other properties were also measured in the present paper.
