Investigations of Dissolving Mechanically Processed Quartz Grains

Abstract

Abstract The dissolution of polycrystalline quartz strained by compression and shear or by impact crushing in 1‐N NaOH lead to different results. The defects of the impact crushed quartz grains, measured as crystallinity by X‐ray methods, are not preferentially concentrated in regions near the surface. It is assumed that in this case the corners and edges of the quartz grains are preferred centers of defects.
