Abstract: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.
