Synthetic amorphous silica typically lack crystalline structures. The method of determination that is normally used is a combination of enrichment of the crystalline portion and X-ray diffraction. The detection limit for this method is less than 0.05 weight percent, and is undershot by all silica grades from Evonik, which are therefore considered completely amorphous.
