High material density, also for applications in the foods industry typical Applications ■ Printing inks ■ Chocolate / Compound chocolates ■ Carbon black preparations SteelBeads Q are food-grade chromium steel grinding beads with very good sphericity. The high density of 7.85 kg/l facilitates the dispersion of high-viscosity products. Q SteelBeads are available with diameters ranging from 2 mm to 6.35 mm. Chemical composition about [in weight %] SteelBeads Q 5 SteelBeads Q 6 SteelBeads Q 8

typical Applications ■ Ferrites ■ Pigment production (e.g. phthalocyanine blue) SteelBeads Micro are spherical cast steel grinding beads of tempered carbon steel. The fine-grained microstructure of the grinding beads give them a long lifetime and high breakage resistance. The SteelBeads Micro are available with diameters ranging from 0.25 mm to 1.4 mm. Chemical composition about [in weight %]

typical Applications Agricultural chemicals GlassBeads are are bubble-free glass grinding beads with a density of 2.5 kg/l. They are especially recommended for wet grinding applications in the low to medium viscosity range. This is also true for applications for which the use of high-quality zirconium oxide grinding beads is no real alternative due to the high costs.

typical Applications Abrasive products Nano products ■ Battery compounds Ceramic products Printing inks Dyestuffs Lacquers ZetaBeads® Plus are yttrium-stabilized high-end zirconium oxide grinding beads of a high density and hardness. In addition, the very good sphericity and polished surface of the grinding beads contribute to an extremely high wear-resistance which prevents product contamination. ZetaBeads® Plus grinding media are ideal for dispersion processes and true comminution of high-quality products.

ZetaBeads® Nano Nano products Abrasives / CMP Pharmaceuticals ZetaBeads® Nano are made of yttrium-stabilized, high-purity zirconium oxide powder. Thanks to their high density and extreme hardness, product contamination is avoided. With diameters ranging from 30 pm to 200 pm, ZetaBeads® Nano are particularly suited for dispersion and wet grinding of high-tech products into the nanometer range. Chemical composition about [in weight %] ZrO2 + HfO2 95 Mechanical properties Density Vickers hardness Young modulus

typical Applications Abrasive products Agricultural chemicals Lacquers Minerals CeraBeads are cerium-stabilized zirconium oxide grinding beads of a high density and hardness. They are suitable for a wide variety of applications that require iron-free processing. CeraBeads optimize your costs and deliver very high grinding efficiency. Chemical composition about [in weight %] Technical Data Available standard qualities Type 0 [mm]

typical Applications ■ Minerals ZsBeads are sintered zirconium silicate grinding beads with a high sphericity. In contrast to grinding beads that are produced in a melting process, ZsBeads are practically free of bubbles and pores. These properties increase wear-resistance and prevent breakage. They are available in various fractional sizes ranging from 0.6 mm to 1.8 mm.
