ZTA6071 Zirconia Toughened Alumina (ZTA) Bead

Zirconia Toughened Alumina (ZTA) Beads Overview

Zirconia Toughened Alumina (ZTA) Beads are advanced ceramic grinding media designed for use in a variety of milling and grinding applications, especially where precision, efficiency, and material purity are essential. These beads are composed primarily of alumina, with zirconium oxide added as a toughening agent. Manufactured through a specialized rolling and high-temperature sintering process, ZTA beads are ideal for dispersing and grinding medium to low viscosity materials in disc sand mills. As a cost-effective zirconium-based grinding media, they are particularly well-suited for the dispersion and grinding of non-metallic materials.
