摘要: 高铝硅酸盐玻璃因具有优异的机械、光学和化学钢化性能而备受关注,但高熔化温度会导致玻璃内气泡和条纹难以消除,这限制了高品质玻璃的制备。As2O3是一种低价、高效的玻璃澄清剂,但受安全因素影响已被禁用。本文选取先前研究中制备的已固化12%(质量分数)As2O3的钠钙玻璃作为澄清剂,利用红外光谱和拉曼光谱分析了含砷钠钙玻璃的引入对高铝硅酸盐玻璃网络结构的影响。此外,采用超景深显微镜,研究了不同As2O3引入量(0%~0.5%,质量分数)对高铝硅酸盐玻璃澄清效果的影响。结果表明,随着含砷钠钙玻璃添加量的增加,高铝硅酸盐玻璃网络结构的聚合度降低。此外,随着As2O3引入量的增加,高铝硅酸盐玻璃中气泡缺陷显著减少;As2O3引入量为0.5%时,澄清效果最佳,气泡熔占比低至0.14%。

Abstract: High-alumina silicate glasses are of interest because of excellent mechanical, optical, and chemical tempering properties, but high melting temperatures can lead to difficulties in removing bubbles and streaks within the glass, which limits the preparation of high-quality glasses. As2O3 is a low-cost and efficient glass clarifier, but As2O3 has been banned due to safety factors. In this paper, sodium calcium glass prepared in a previous study that had solidified 12% (mass fraction) As2O3 was selected as a clarifier, and the effect of the introduction of arsenic-containing soda-lime glass on the network structure of high-alumina silicate glass was analyzed by FTIR spectra and Raman spectra. In addition, the effects of different As2O3 introduction amounts (0% to 0.5%, mass fraction) on the clarification effect of high-alumina silicate glass were investigated by using super depth-of-field microscopy. The results show that the polymerization of the network structure of high-alumina silicate glass decreases with the increase of the addition of arsenic-containing soda-lime glass. In addition, with the increase of As2O3 introduction amount, the bubble defects in high-alumina silicate glass are significantly reduced. When As2O3 introduction amount is 0.5%, the clarification effect is the best, and the bubble fusion ratio is as low as 0.14%.
