Mechanical modification of silica powders

Abstract. Two types of silica powder with different structures, one crystalline (C1) and one amorphous (A1) were mechanically treated using a planetary type mill. Three different rotation speeds (100, 200, 300 rpm), milling times (15, 30, 60 min) and ball sizes (1, 5, 10 mm) were used. The structure and morphology of the powders did not change ...
