Product Overview
|
| ATOMFAIR® Yttria-Stabilized Zirconia Planetary Mill Jar (YSZ Grinding Jar) is manufactured from high-density yttria-stabilized zirconia (YSZ 3mol% density 6.0 g/cm³ HV≥1250 Mohs 8.5) via high-temperature sintering to achieve a fully densified, pore-free structure with exceptional toughness, ultra-low wear, acid-alkali corrosion resistance, and zero heavy metal release. Purpose-built for high-purity nano grinding zero metal contamination applications, this non-metallic ceramic jar releases virtually no impurities during grinding—making it the industry-standard choice for lithium battery materials (NCM, LFP, Si-C anode), MLCC electronic ceramics, and pharmaceutical powders where metal contamination is unacceptable. The sintered non-porous low wear acid-alkali resistant structure delivers hardness and toughness far superior to alumina jars, with an exceptionally long service life under continuous ultrafine grinding. The high-density material (6.0 g/cm³) combined with planetary high-energy impact enables rapid micron-to-nanometer particle refinement. Standard volumes from 50 ml to 5 L are compatible with mainstream laboratory planetary ball mills; 4 L and 5 L large-capacity jars feature outer stainless steel jackets for enhanced impact resistance. Custom volumes and dimensions are available upon request at inquiry@atomfair.com. |

Key Features & Advantages
|
- Low-Contamination High-Purity Grinding—Industry Standard for Li-Ion Battery & Electronics: Non-metallic YSZ ceramic releases virtually no impurities during grinding—zero heavy metal contamination—making it the definitive jar choice for NCM/LFP cathode materials, MLCC dielectric powders, and pharmaceutical active ingredients where metal contamination is unacceptable.
- Superior Wear Resistance and Toughness—Far Exceeds Alumina Jars: Hardness (Mohs 8.5, HV≥1250) combined with phase-transformation toughening delivers wear life and impact resistance significantly beyond alumina jars, with ultra-low wear rates ensuring exceptionally long service life under continuous ultrafine grinding.
- Excellent Chemical Stability—Universal Acid-Alkali-Solvent Compatibility: The dense sintered YSZ structure resists corrosion from most acids, alkalis, and organic solvents, enabling both dry and wet grinding across diverse chemical environments without jar degradation or impurity leaching.
- High Grinding Efficiency with 6.0 g/cm³ Density: The high-density zirconia material combined with planetary high-energy revolution/rotation impact delivers rapid micron-to-nanometer particle refinement, significantly reducing grinding time compared to lower-density jar materials.

APPLICATION SCOPE: Lithium battery industry: NCM ternary, LFP, and Si-C anode electrode powder ultrafine grinding—the industry-standard jar for eliminating iron and metal impurity contamination. Electronic ceramics: MLCC dielectric powders, piezoelectric ceramics, thermistor ceramics, and electronic functional powders. Pharmaceutical and food: active pharmaceutical ingredients, health supplement ultrafine powders, and food-grade colorants—zero heavy metal residue. High-end pigments and coatings: nano-scale color pastes and inorganic functional pigments ensuring pure coloration without foreign tint. Advanced ceramics and refractory materials: silicon carbide, aluminum nitride, and high-purity ceramic powders. Catalytic materials: catalyst carriers and nano-catalytic powder R&D. Supports dry grinding, wet grinding, and vacuum-sealed inert atmosphere (N₂/Ar) oxygen-free grinding for oxidation-sensitive metal powders. Compatible with planetary high-energy ball milling, mechanical alloying, and solid-phase synthesis experiments.
SUPPLEMENTARY NOTES: 4 L and 5 L large-capacity YSZ jars feature outer stainless steel jackets for enhanced impact resistance and anti-fracture protection. Non-standard volumes and custom outer diameter dimensions are available upon request. Vacuum sealing components for inert atmosphere grinding are available as optional accessories.
IMPORTANT NOTICE: Standard sizes are compatible with mainstream laboratory planetary ball mills. For 4 L and 5 L stainless-steel-jacketed jars, confirm compatibility with your planetary mill’s clamp dimensions before ordering. Vacuum-sealed jar configurations require compatible vacuum pump connections for inert atmosphere operation. For custom volumes, dimensions, or vacuum jar configurations, please contact us at inquiry@atomfair.com.
