Ceramic Beads JS95 Yttria Stabilized Zirconia Beads

Product Overview

Ceramic Beads JS95 is our yttria stabilized zirconia beads, it is high-end ultra-fine grinding media made of high-purity zirconia powder with yttria as stabilizer. Produced via nano-powder preparation, rolling forming or droplet forming and high-temperature dense sintering. Featuring tetragonal toughened structure, the beads combine ultra-high hardness and excellent toughness. It is the optimal media for wet nano-scale grinding, dispersion and polishing, widely used in new energy lithium batteries, electronic pastes, high-end inks & coatings, fine ceramics, pharmaceuticals and cosmetics.

Advantages

High density for boosted grinding efficiency
True density ≥6.0g/cm³, stronger impact force quickly breaks material agglomerates to reach nano fineness, lifting production efficiency by over 40%.
Ultra-low self-abrasion with high hardness & toughness
Tetragonal phase transformation toughening technology, Self-abrasion is at ppm level, minimizing impurity precipitation and guaranteeing material purity.
Strong chemical inertness with zero contamination risk
Resist strong acid & alkali and all kinds of organic solvents, no metal or silicon precipitation.
Lower comprehensive production cost
Service life is 30-50 times of glass beads and 2-3 times of zircon silicate beads, reducing replacement frequency, downtime and consumable cost.
