Zirconia Toughened Alumina (ZTA) BeadsDURA-32

 

lDescription

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.

lApplications

Minerals industry;

Chemical industries;

Fillers: filler of paper, plastic and rubber.

lSpecialty

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.
