Description:
Alumina Toughened Zirconia (ATZ) bead was 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.

Specialty :
-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.turbine and pins.

Application :
-Inks: printing inks such as gravure inks, 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: TiO,, CaCO, and ceramic glazing.
