Dependence of particle size distribution upon brittleness in glass

The size reduction of glasses is dependent on the impact energy and their brittleness. In milling, the particle size distribution is especially related to the glass brittleness, which can be predicted by the experimentally determined elastic modulus. The correlation of glass mechanical proper-ties with particle size distribution during dry milling was investigated. The D50-90 particle size distribution and mean particle size were related to the glass brittleness. We suggest that the relationship between frit size distribution and brittleness should be considered for efficient pulverization, and further that the glass brittleness can be predicted by the elastic modulus of glasses.
