石英玻璃的性能与化学纯度密切相关，其化学纯度会受到原材料和制备工艺的影响。天然石英晶体在 生长的过程会不可避免的产生各种缺陷，而玻璃制品在制备过程中，受到制备工艺和操作环境的限制，可 能会引入各种杂质、产生残余应力，进而引发结构缺陷和宏观缺陷的产生。 来源：日本东曹株式会社 石英玻璃中常见的缺陷 宏观缺陷 石英玻璃中的宏观缺陷通常是由原料不纯或制备工艺不当引起的，常见的宏观缺 陷包括气泡、包裹 物、条纹以及热应力导致的开裂等。熔融石英的粘度非常大，因此气泡在其中很难被去除。气泡主要来源 于水晶粉颗粒内含的天然气液包裹体，或者是水晶粉颗粒之间孔隙所裹带的空气、燃烧气等，其产生还与 石英玻璃的熔制过程有关，不当的熔制方式会导致内部未熔化的石英原料被外表面的熔融石英所包裹，从 而阻碍了气泡的逸出。石英玻璃的热应力出现在冷却过程中，是由玻璃不同部位的温差引起的。热应力不 均匀会导致石英玻璃的光学不均匀性增加，热应力过高时甚至会导致石英玻璃的开裂。与结构缺陷不同， 宏观缺陷的产生往往意味着石英玻璃产品的报废，因此在实际生产中需要对制备工艺进行严格的控制。 结构缺陷 石英玻璃的结构缺陷是由于Si-O原子网格中引入了杂质， ...
