Product Description

Silicon nitride ceramic is an advanced engineering material renowned for its exceptional mechanical strength, thermal stability, and wear resistance. Its unique covalent-bonded Si₃N₄ structure makes it ideal for demanding applications in industries ranging from aerospace to biomedical engineering.

Key Properties

Mechanical Strength: High flexural strength (800-1000 MPa) and fracture toughness (6-8 MPa·m¹/²), outperforming alumina ceramics.
Thermal Performance: Retains strength at 1200-1400°C with excellent thermal shock resistance.
Chemical Stability: Resistant to acids, alkalis, and oxidation (except HF).
Electrical & Biocompatibility: Insulating (resistivity >10¹⁴ Ω·cm) and biocompatible for medical implants.

Manufacturing Methods

Reaction Bonding (RBSN): Cost-effective but porous.
Hot Pressing (HPSN): High density, limited shapes.
Gas Pressure Sintering (GPSN): Balanced performance with sintering aids (e.g., Y₂O₃).
3D Printing: Emerging for complex geometries.
