Abstract
一种高弗尔德常数磁敏旋光玻璃的制备方法是采用Tb2O3-Al2O3-B2O3-SiO2系磁光玻璃，并采用二次熔融技术进行熔炼，所制备的磁光玻璃的弗尔德常数为0.26-0.38(波长为632.8nm)，可用于可见光、近红外波段，具有优良的拉丝性能。
Description
本发明属磁光玻璃制备方法的改进。
磁敏旋光玻璃是一种新兴的高科技领域中重要的功能材料，根据法拉第旋光效应(即磁光效应)，磁光玻璃可以制作光学隔璃器、磁光调制器、磁光开关和高压输电线路中大电流测量传感器头等功能器件；用磁光玻璃拉制出碰敏保偏光纤，在光纤陀螺制导、偏振光保密通信、实时图象识别，以及高压、防火防爆、有毒及放射性环境中磁场检测等领域有重要应用。而表征磁光玻璃性能的最重要参数为弗尔德常数，根据磁光效应，当光平行于磁场方向而通过磁光玻璃时，将发生偏振面的旋转，而旋转角度θ＝V·L·H，式中V为弗尔德常数(分/奥斯特·厘米)，又名顺磁旋光系数，L为旋光玻璃长度，H为磁场强度，当L和H为定值时，V值越高Θ角就越大，其旋光性能就越好。
目前国际上性能最好的磁光玻璃是美日跨国公司HOYA CO.生产的FR-5玻璃，其产品说明书中叙述FR-5玻璃的弗尔德常数为0.242(波长为632.8nm)。1988年，有报导该公司正在试制性能进一步改善的FR-6玻璃，但未报导其性能参数，参见Donald Wilson，Laser Focus/electra-optics，Dec.103(1988)。
本发明的目的在于提供一种高弗尔德常数的磁敏旋光玻璃制备方法。
本发明的特征在于：玻璃为Tb2O3-Al2O3-B2O3-SiO2系磁光玻璃，其化学组成为(重量百分比)：Tb2O356-69，SiO26-24，B2O36-14，Al2O33-12，MgO0-4，BaO0-8，其熔炼工艺采用二次熔融技术。其制备的具体方法步骤为：原料采用分析纯和光谱纯的化学试剂，其原料的选择及用量为(重量百分比)，Tb4O757-70，SiO24-29，H3BO39-27，AL(OH)34-22，Mg(OH)20-6，BaCO30-11，除Tb4O7和SiO2外，其他原料可选择替换，如H3BO3可选择B2O3，Al(OH)3可选择Al2O3，Mg(OH)2可选择MgO，BaCO3可选择BaO等等，其替换后的用量可根据上述比例计算；经研磨混合均匀后，用铂坩锅进行二次熔炼，第一次在1520-1560℃温度下熔化、澄清、搅拌均化二小时，第二次在1450-1550℃温度下，将玻璃中析出物再次熔融、澄清、搅拌均化，然后浇注在钢模中，再经退火即得到成品玻璃。
本发明所采用的二次熔融技术具有以下优点，比一次熔融温度可低50-80℃，而且其熔融时间可缩短2-3小时。所制备的磁光玻璃具有性能稳定、不失透、化学性质稳定、易于扩大生产等优点，其弗尔德常数为0.26-0.38(波长为632.8nm)，相比FR-5玻璃高出38％，测得的其它性能参数为：折射率ND＝1.74928，NC＝1.74497，NF＝1.75961，阿贝数51.18，软化点约780℃，这些参数均优于FR-5玻璃。本发明所制备的磁光玻璃可用于可见光、近红外波段，具有优良的拉丝性能。
