Alumina Toughened Zirconia (ATZ) Beads : DURA 52


DURA-52 Alumina Toughened Zirconia (ATZ) bead was dropped and granulated from the ultra fine zirconium dioxide and alumina powder. The consistent micro poly-crystal benefits high compressive strength and wear resistance of beads. Although there is a lower density than T-TZP (Yttria-Tetragonal Zirconia Polycristal ), the lower unit cost is an obvious plus. It can replace it in more application and is competent the mills with high tip speed up to 14m/s.


—Inks: printing inks such as gravure ink, screen inks and offset inks; inkjet inks, UV inks and water-based inks;

—Coating and paints: prime and top coating of auto, coiling coating, paper coating, emulsion paint and marine paint;

—Pigments: TiO2, CaCO3 and ceramic glazing.


—The specific gravity and hardness are closed the Y-TZP beads;

—Higher wear rate than Y-TZP, but lower unit cost;

—Can handling abrasive concentrates and high viscosity slurries;

—Matching mills: general stirred mills with disc and pins.
