| 摘 要： | 用差热分析（ＤＴＡ）、Ｘ射线衍射分析（ＸＲＤ）方法研究了Ｙ２Ｏ３和Ｇｄ２Ｏ３对７０Ｂ２Ｏ３２５Ｌａ２Ｏ３５ＺｎＯ（ｍｏｌ％）玻璃析晶性能的影响；用梯温炉测定比较了Ｙ２Ｏ３和Ｇｄ２Ｏ３对玻璃失透倾向的影响；用红外光谱（ＩＲ）研究了Ｙ２Ｏ３和Ｇｄ２Ｏ３在玻璃中的结构作用。结果表明，适量用Ｙ２Ｏ３或Ｇｄ２Ｏ３取代Ｌａ２Ｏ３可以减轻玻璃的失透倾向，但没有改变玻璃的析晶相。玻璃的析晶相是ＬａＢ３Ｏ６，Ｙ２Ｏ３和Ｇｄ２Ｏ３在玻璃结构中为网络修饰体。玻璃的折射率ｎｄ高于１．７０，色散系数υ低于５５。

| Abstract: | Effects of Y2O3 and Gd2O3 on the crystallization property of 70B2O3 25La2O3 5ZnO (mol% ) glass were studied using Differential Thermal Analysis (DTA) and X-Ray Diffraction (XRO).The influence of Y2O3 and Gd2O3 on glass devitrification was compared using a gradient furnace. The structural role of Y2O3 and Gd2O3 in the glass was discussed using Infrared spectroscopy (IR). The results indicated that glass devitrification degree could be decreased by replacing La2O3 with suitable ammount of Y2O3 or Gd2O3. However, the crystalline phase of the glass remained unchanged and it wasfound to be LaB3O6. Both Y2O3 and Gd2O3 act as modifiers in the glass structure. These glasses have high refractive indices (nd>1.70) and low dispersion coefficients (v<55). |
