Product Description
Product Description

Aluminum oxide (Al2O3) ceramic
Aluminum oxide (Al2O3) ceramic is indeed a critical material in ballistic protection due to its exceptional mechanical properties.
1. Bulletproof Mechanism
High Hardness (Mohs 9): Alumina ceramics can shatter incoming projectiles by exceeding their hardness, dispersing kinetic energy through brittle fracture .
Fracture Toughness: Despite being brittle, 99% alumina ceramics absorb energy via controlled cracking, slowing the bullet before secondary layers (e.g., aramid fibers) capture residual fragments .
Compressive Strength: Withstands high-stress impacts (e.g., ~2-4 GPa), crucial for resisting deformation from high-velocity rounds .

2. Key Properties
Wear Resistance: Ideal for multi-hit scenarios in armor systems.
Thermal Stability: Maintains performance under extreme conditions (e.g., vehicle armor in desert climates).
Lightweight: Compared to metals, alumina reduces weight while offering comparable protection (e.g., for body armor) .
