The whole process of manufacturing the transparent quartzglass was studied using refined high purity silica sand. Impurity of this refined silica sand is below 500644g/g. On the other hand, the physical properties of the transparent quartz glass which was made of this high purity silica sand reach the same level as that made of natural crystals.
