Effect of the Gel Pulverizing Process on the Morphology of the As Synthesized Quartz Powder

The gel-pulverizing process on the morphology of the as-synthesized quartz powders. Three hours after the ion exchange process, SiO2 sol was changed into a single lump of gel; when subjected to the gel-pulverizing process, the gel lump was separated into many gel lumps of several mm. In addition, the morphology of the quartz powder synthesized via the gel-pulverizing process was very different from that produced without the gel-pulverizing process, as is shown in the SEM images. The morphology of the quartz powder synthesized from the gel without the pulverizing process was rod-shaped, and their widths and lengths were a few hundred micrometers and a few centimeters, respectively. On the other hand, the powder synthesized with the gel = pulverizing process was granular-shaped, and their widths and lengths ranged from 50 to 400 μm�m. Interestingly, however, no difference in the crystallinities of the two groups of quartz powders was observed, as they showed the same peaks in the rocking curve of the XRD pattern as normal SiO2.
