摘要
本文讨论了ＰｂＯ—Ｂｉ２Ｏ３—Ｂ２Ｏ３玻璃中引入少量Ｃｒ２Ｏ３对玻璃的颜色及析晶性能的影响。在ＰｂＯ—Ｂｉ２Ｏ３—Ｂ２Ｏ３玻璃的配合料引入０．０１—２（ｗｔ％）的Ｃｒ２Ｏ３随着Ｃｒ２Ｏ３含量的变化，玻璃颜色从橙黄、橙红到深红变化，直至析晶、失透。当Ｃｒ２Ｏ３引入量在０．２５～０．５（ｗｔ％）时，适当控制热处理条件，可得到含有粗大晶体的红色玻璃，ＥＤＳ测试表明，析出矿物的化学组成为Ａｌ和Ｋ，其原子比为１：１。
This paper deals with the coloration and nucleation effects of PbO-Bi2O-B2O3 glass with trace amount of Cr2O3 addition . The experimental results showed that thevariation of color from yellow. orange, red . dark brown to total devitrification were appearedwit the addition of 0. 01￣2 (wt%) Cr2O3 With the suitable control of heat treatment. heavycrystallization was produced with 0. 25￣0. 5 (wt%) Cr2O3 added. The EDS measurementshowed that the nucleated compound contens Al and K with atomic ratio of 1: 1.
