Material: Yttria-stabilized zirconia (ZrO₂ + Y₂O₃)
Hardness: ~8.5 Mohs - 2nd hardest after tungsten carbide
Density: ~6.0 g/cm³ - heavier than agate/steel
Key Advantages:
✔️ Extreme wear resistance - longest lifespan among ceramic jars
✔️ High fracture toughness - more durable than agate/alumina
✔️ Chemically inert - resistant to most acids/alkalis
✔️ Zero metal contamination - ideal for trace analysis
✔️ Suitable for ultra-hard materials (e.g., silicon carbide, tungsten)
