摘要
研究了PbBr2 -PbCl2 -PbF2 -PbO -P2 O5系统的玻璃在熔融过程中的变化。发现在玻璃的熔制过程中 ,元素P、Pb和Br的损失量最大。化学分析和理论计算表明 ,这些元素是以PbCl2 、PbBr2 和P2 O5的形式挥发的。而且 ,随着配料成分中含量的增加 ,PbCl2 、PbBr2 和P2 O5的挥发量也随之增加。
Composition change during the melting process of some glasses in the PbBr 2-PbCl 2-PbF 2-PbO-P 2O 5 system was studied.Results show that there was a remarkable discordance between the batch composition and the analyzed composition.Large amount of P, Br, Pb were lost mainly in the form of PbBr 2,PbCl 2 and P 2O 5.When a sample contains high content of Br and Cl, the loss of them is remarkable.The content of O is influenced by two factors.
