Effects of grinding of the feldspar in the sintering using a planetary ball mill

The feldspar mineral has been ground using a planetary ball mill with a stainless steel ball and bowl. During grinding, the ground sample gets contaminated with Fe from ball and bowl wall, the same as the amorphization and agglomeration of fine particles that increase as grinding time progresses. The effect of sintering is carried out in the recrystallization and consolidation of the mechanical activation of anorthoclase feldspar to transform albite and anorthite, and iron to hematite in the glazed matrix.
