Kinetics of dry grinding of quartz glass (fused quartz ...
We studied the kinetics of dry grinding of quartz glass in a ball mill. We determined the dispersion of the powders at different stages of grinding and showed that it is markedly retarded with the attainment of a specific surface in the powder of about 14,000 cm 2 /g.. The dispersion and degree of polydispersion of the powder for different grinding times are characterized.
