It is with the earth rare element cerium so cerium stabilized zirconia bead has the biggest specific gravity in all zirconia beads series and it is very suitable for some special industries and grinding materials, especially for milling and dispersing high viscosity pastes and high purity products.
(1).Wear-resistant, corrosion-resistant products: paints, textiles, paints, printing and dyeing;
(2). High strength, high toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics;
(3).To prevents pollution: medicine, food, cosmetics;
(4).Ceramics: Electronic ceramics, refractory ceramics, structural ceramics.
Features:
It has a gem-like hardness and density.Micro-structure of delicate, uniform, dense ceramics of the Quartet. Its excellent wear resistance and fracture toughness is particularly suited for grinding and dispersing high-solid-phase high-viscosity, high hardness of the paste.
(1).Long working life: 30 times longer life than glass beads, 6 times than zirconium silicate beads.
(2)High grindingefficiency: around 6 times than glass beads; 2 times than zirconium silicate bead
(3).Excellent wear resistance and fracture toughness.
