DURA ZTA Bead DURA-32

DURA ZTA Bead DURA-32 Zirconia Toughened Alumina (ZTA) bead was sintered from alumina powder and zirconium silicate powder. Compared to the alumina beads, it has a higher fracture toughness and lower hardness. It is an economic ceramic bead to replace Kaolin bead, silica sand and other natural grinding media.

    Features & Benefits

    Specialty
    • Higher toughness than alumina beads: break resistance
    • Lower surface friction coefficient and hardness: lower wear and tear to the internal parts of bead mills
    • Low wear rate of beads: increase whiteness and coloury of slurries.
    • Matching mills: lower intensity mills.
