摘要/Abstract

摘要： 以Ⅲ类石英玻璃为研究对象,从实际试验熔制角度,探究了不同熔制气氛下石英玻璃沿径向方向上羟基的含量及分布情况,并对羟基的形成原因及稳定性进行了初步分析。结果表明,不同熔制气氛下的石英玻璃中羟基分布均呈现出中间高边缘低,中性气氛中羟基含量最低,还原气氛中羟基含量最高。停料空烧方法可改善原有氧化气氛中石英玻璃产率较低的情况,但会导致砣面表面不平整,边缘羟基含量大幅增加。不同熔制气氛下的石英玻璃经高温热处理后羟基含量趋于一致,还原气氛下的降幅最大,约55%。

Abstract: Taking type Ⅲ silica glass as the research object, from the perspective of actual experiment and melting, the content and distribution of hydroxyl along the radial direction in silica glass under different melting atmospheres were explored. A preliminary analysis was made on the formation and stability of the hydroxyl. Experimental results show that distribution of hydroxyl in silica glass under different melting atmospheres is high in the middle and low in the edge along the radial direction, and the content of hydroxyl is the lowest in neutral atmosphere and the highest in reducing atmosphere. The long-term stoppage and empty burning method improves the situation that the silica glass yield is low in the original oxidizing atmosphere, but it leads to uneven surface of the ingot surface, and the edge hydroxyl content increases significantly. The hydroxyl content of silica glass in different melting atmospheres tends to be the same after high-temperature heat treatment, and the decrease rate is the largest under reducing atmosphere, about 55%.

Key words: silica glass, silicon dioxide, hydroxyl, melting atmosphere, stability
