Customized Silicon Nitride Components
Silicon Nitride (Si₃N₄) is a high-performance engineering ceramic combining high mechanical strength, toughness, low density and low thermal expansion. Its mechanical and thermal characteristics make it particularly suitable for components exposed to demanding mechanical loads and temperature changes.
Key Properties
- High mechanical strength
- High fracture toughness compared with many technical ceramics
- High hardness and wear resistance
- Low density
- Low thermal expansion
- Excellent thermal-shock resistance
- Electrical insulation
Typical Material Properties
| Property | Unit | Typical Reference Value |
| Density | g/cm³ | ~3.2 |
| Flexural Strength | MPa | ~700–850 |
| Fracture Toughness | MPa·m½ | ~6–7 |
| Young’s Modulus | GPa | ~280–320 |
| Hardness | HV | ~1550 reference |
| Thermal Conductivity | W/m·K | Grade dependent; selected high-thermal-conductivity grades can reach ~90 |
| CTE | 10⁻⁶/K | ~3.1–3.3 |
| Operating Temperature | °C | Grade and atmosphere dependent |
Technical note: Values are typical reference values and can vary with material grade, composition, microstructure and manufacturing process. Final specifications are confirmed for each project.
