The removal of impurities in gas and liquid inclusions in quartz by acid and alkali corrosion belongs to the technical field of deep processing of non-metallic minerals. The gas liquid inclusions in natural quartz are the root of the main bubble defects in the glass of fused silica. Therefore, the removal of gas liquid inclusions in quartz materials is of great benefit to reduce or eliminate the bubble content in the glass of fused silica. This technique is characterized by using the principle of opaque quartz particles containing fluid inclusions in natural quartz with gas-liquid inclusions transparent quartz particles differences in acid or alkaline medium corrosion to remove gas liquid inclusions to quartz. The invention can make some cheap and cheap natural quartz raw material processed by this method instead of high quality crystal to make transparent quartz melt glass.

石英熔体玻璃在现代光纤、电子、电光源等高新
具有越来越广泛的用途，但由于石英熔体粘度极高，石英原料颗粒内部包含的气液包裹体在石英熔体中形成气泡后极难排出，所以目前国内石英熔体玻璃只能用昂贵的含气液包裹体少的天然水晶作为原料，没有工艺和方法去除石英中气液包裹体杂质。本专利技术目的是使一些低档价廉的天然石英原料经此工艺方法处理代替优质水晶制造透明石英熔体玻璃。自然界除优质水晶外，其它种类的石英(如从花岗岩、花岗伟晶岩中提取的石英，变质岩石中提取的石英，多期重结晶的脉石英，与云母、蛭石共生的石英)破碎成颗粒后，部分为不含气液包裹体杂质类似于水晶的透明石英颗粒，部分为含较多气液包裹体杂质的半透明或不透明石英颗粒。本专利技术就是利用透明颗粒与不透明或半透明颗粒在酸、碱介质中的差异腐蚀达到去除不透明或半透明颗粒，从而去除或减少石英中气液包裹体杂质。本专利技术要案1、天然石英破碎成颗粒后必须含有一定数量的透明石英颗粒。如花岗岩型石英，花岗伟晶岩型石英，变质岩型石英，多期重结晶的脉石英，与云母、蛭石共生的石英等可满足本工艺使用条件要求。2、满足上述条件要求的天然石英破碎成颗粒...
