Effect of the Sample Concentration on the Submicrometer ...

Wet ultra fine grinding of a calcite powder has been investigated in a stirred ball mill with respect to the effect of slurry concentration. The grinding rate on the submicrometer range was measured and the grinding constant on the grinding rate (K) in the grinding kinetics equation was examined.It is observed that the grinding rate for calcite in the submicrometer size range is different for ...

1. Introduction

In this report, ibuprofen was attempted to form hybrid mesocrystals with calcium carbonate crystals. Two polymorphs of calcium carbonate (aragonite and calcite) were used during the solid-state process of ball milling. Structural analyses confirmed the mesocrystal formation of ibuprofen with aragonite but not with calcite.
