ZetaBeads® Plus

Yttrium-stabilized zirconium oxide grinding beads (High-end quality)


ZetaBeads® Plus are yttrium-stabilized high-end zirconium oxide grinding beads of a high density and hardness. In addition, the very good roundness and polished surface of the grinding beads contribute to an extremely high wearresistance with practically no product contamination. ZetaBeads® Plus grinding media are ideal for dispersion processes and real comminution of materials and products in the nano particle range.
