Note: Grain size determination-Grinding 24 minutes( dry grinding),the ball
material ratio 10:1,using laser particle size analyzer (MS 2000),
measuring median diameter(D50).Normally it needs ultrasound for 1 minute and
then to be measured.
A means activity (Activated) suitable for production of grinding media.
M means a smaller microcrystalline product than grain size.
