含Al2O3的碲铌铅玻璃的性能研究

摘要

研究了含Al203的碲铌铅玻璃的性能并将之与不合Al2O3的玻璃的性能作了比较.结果表明，在碲铌铅玻璃中掺入Al2O3后，玻璃的密度和红外透过性能有所降低，玻璃转变温度升高，但此举并不改变其它组分对其性能变化趋势的影响.%The properties of the PbO-NbO2.5-TeO2 glass containing Al2O3 were studied and compared with Al2O3-free glass. The result shows when A12O3 is introduced, the glass density falls, the IR transmission is deteriorated, but the transformation temperature rises.
