摘要:

在钡镓锗酸盐玻璃中引入氟化物,研究了BaF2-Ga2O3-GeO2和BaF2-GaF3-GeO2系统的玻璃形成区,并采用DTA分析方法研究了成分对玻璃热性质的影响。研究表明,随玻璃组分中氟化物组分数增加,玻璃形成区减小;在含氟化物的钡镓锗系统中,析晶温度Tx随Ga含量增加出现最大值,转变温度Tg出现极小值;在Ga含量不变的情况下,Tx随BaF2含量增加也出现极大值;以摩尔百分数计,对于BaF2-Ga2O3-GeO2系统,20BaF2系列玻璃的最佳Ga2O3含量约为15%,15Ga2O3系列玻璃的最佳BaF2含量约为15%;在BaF2-GaF3-GeO2系统中,10BaF2系列玻璃的最佳GaF3含量约为20%,15 GaF3系列玻璃的最佳BaF2含量约为10%。

Fluoride beng Introduced into the barium gallium germanate glass, the glass-forming regions of BaF2-Ga2O3-GeO2 and BaF2-GaF3-GeO2 system were investigated, and the effects of components on the thermal properties of glass were studied using the DTA analysis method. Results show that, the glass-forming region decreases with the increase of fluoride component number. For barium gallium germanium system with fluoride, crystallization temperature of Tx has a maximum value with the increase of Ga content, the transition temperature Tg is minimum. When the content of Ga under the condition of constant, Tx also appears the maximum value with the BaF2 content. In molar percentage, for the BaF2-Ga2O3-GeO2 system, the optimal content of Ga2O3 in 20BaF2 series glass is about 15%, and the optimum BaF2 content of 15Ga2O3 series glass is about 15%. In the BaF2-GaF3-GeO2 system, the optimum GaF3 content of 10BaF2 series glass is about 20%, and the optimum BaF2 content of 15 GaF3 series glass is about 10%.
