Product Description
Silicon Nitride Ceramic Plate Overview
Silicon Nitride (Si3N4) is an advanced ceramic material engineered for high-temperature applications, maintaining exceptional strength from room temperature up to 1200°C. Its low coefficient of thermal expansion provides superior thermal shock resistance, while excellent thermal conductivity ensures optimal performance in demanding environments.
Key Material Properties
- High temperature strength maintained up to 1200°C
- Superior thermal shock resistance
- Excellent wear resistance and fracture toughness
- Mechanical fatigue and creep resistance
- Excellent non-wetting properties with good oxidation resistance
Ceramic Tray & Substrate Advantages
- High thermal conductivity up to 70 W/m·K (3x alumina substrate)
- Thermal expansion coefficient (3.1×10⁻⁶/°C) matches semiconductor silicon
- Bending strength twice that of alumina substrates
- Excellent electrical performance with high insulation resistance
- Multi-layer wiring capability for package miniaturization
- Exceptional thermal shock resistance: 10,000 cycles from 0°C to 200°C
- Chemical resistance to oxidation, acid, and alkali corrosion
- Service lifespan up to 10 years
