✔ Superior Fracture Toughness (Best Among Ceramics)
Toughness (KIC): 8–10 MPa·m¹/² (higher than alumina & Si₃N₄, near tungsten carbide levels).

Resists chipping/cracking – Suitable for high-impact milling (e.g., planetary mills).

✔ Moderate Density for Efficient Grinding
Density: 6.0 g/cm³ (lighter than WC but heavier than Si₃N₄ or alumina).

Optimized kinetic energy – Efficient for both brittle and hard materials.
