摘要：

A method for forming high purity silica articles. The high purity silica articles can be particularly suitable for forming packaging such as packaging for pharmaceutical applications. The method for forming high purity silica articles can comprise, in one embodiment, (a) forming a fused quartz melt from a SiO2 raw material (b) forming a quartz tube from the fused quartz melt (c) treating the quartz tube with an acid composition (d) heat treating the quartz tube subsequent to treating with the acid composition and (e) optionally treating the quartz article with an acid composition subsequent to the heat treating operation. The method can enhance the purity of silica glass articles and products made therefrom.
