Summary

Freshly ground quartz and naturally occurring quartz in ball clay were examined by means of X-ray diffraction and scanning electron microscopy. The crystallinity of quartz was obtained by using the Murata index. Freshly ground quartz has a higher crystallinity index than geologically aged quartz in ball clay. The scanning electron microscopy images of natural clay indicate stronger quartz-kaolin interaction than in quartz-kaolin mixture. Overall data show that naturally occurring quartz in ball clay is materially different wan freshly ground quartz.
