Ceramic beads made of aluminium-silicon oxide Maheshwari® A 99.3 aluminum oxide beads have a high degree of purity with an Al2O3 content of > 99% and with secondary components of < 0.7%. These beads are ideal for use in agitator bead mills and in the wet grinding of aluminum oxide raw materials, e.g. for technical components, coatings and for high-quality paints and inks. The advantage is the availability of beads down to 0.5mm-60mm. Technical Data: High purity ≥ 99.3 % Al2O3 Specific Weight ≥ 3.8 kg/dm3 Bulk Density ≥ 2.3 kg/dm3 Roundness ≥ 0.93 (ratio width/length (xmin/xmax)) Colour: White Fields of application In the mining industry A 99.3 ceramic beads are used for the grinding of minerals and precious metals. Quality attributes The ceramic beads type A 99.3 have a dense sintered structure, a smooth surface, high roundness and high hardness.
