摘要
高纯石英玻璃具有良好的物理化学性能,被广泛应用于各种高科技行业,然而天然水晶矿产资源日渐枯竭,采用硅石矿替代天然水晶生产高纯石英玻璃是行之有效的方法。由于硅石矿中原子的排列方式和受地质因素影响其内部存在气液包裹体,这是硅石矿制备高纯石英玻璃产生气泡的主要原因,它的存在直接影响着石英玻璃的纯度及应用性能。气液包裹体的剔除是硅石矿替代天然水晶生产高纯石英玻璃的关键。综合阐述了国内外常用气液包裹体的剔除方法:机械破碎法、热爆裂法、酸蚀法、高温氯化脱气法以及微波法,这些方法能够对气液包裹体起到较好的剔除效果,但存在一定的局限性。最后,对气液包裹体剔除法的发展方向进行了展望。
High-grade transparent quartz material has good physical and chemical properties and it is widely used in various high-tech industries.With the diminishing natural crystal mineral resources,it is an effective and feasible method to produce high-grade quartz material by using silicon ore instead of natural crystal.Because of the arrangement of atoms and geological cause,there exist gas-liquid inclusions in silica ore.Gas-liquid inclusion is the main cause of bubbles in quartz glass products prepared by silica ore,and gas-liquid inclusion will directly affect the purity and application performance of quartz glass.Removing gas-liquid inclusions is the key to producing high-grade fully transparent quartz materials with silica ores.The methods of removing gas-liquid inclusions were comprehensively introduced,including mechanical crushing method,thermal explosion method,acid etching method,high-temperature chlorination with degassing method and microwave method.These methods could remove gas-liquid inclusions effectively,but with some limitations.Finally,the development direction of gas-liquid inclusion elimination method was prospected.
