Silicon Nitride Ceramic Substrate - China

Advantages of silicon nitride ceramic substrates Silicon nitride ceramic substrate has a low thermal expansion coefficient and high thermal conductivity, so it has excellent thermal shock resistance.

The hot-pressed sintered silicon nitride will not break even if it is put into cold water after being heated to 1000°C.

Applications of silicon nitride ceramics Silicon nitride ceramic has a low thermal expansion coefficient and high thermal conductivity, so it has excellent thermal shock resistance.

The hot-pressed sintered silicon nitride will not break even if it is put into cold water after being heated to 1000°C.

At temperatures that are not too high, silicon nitride has high strength and impact resistance, but it will be damaged as the use time increases above 1200°C, reducing its strength.

It is more prone to fatigue damage above 1450°C.

Therefore, the operating temperature of Si3N4 generally does not exceed 1300°C.

Therefore silicon nitride has been widely used in: rotating ball and roller bearings; Engine parts: valves, rocker arm pads, sealing surfaces; Induction heating coil holder; Turbine blades, blades, buckets; welding and brazing fixtures; Heating element assembly; welding positioner; Precision shafts and bushings in high-wear environments; Thermocouple jackets and tubes; Semiconductor process equipment.

Silicon nitride ceramic properties 1 - High strength in a wide temperature range; 2 - High fracture toughness; 3 - Good bending strength; 4 - Resistant to mechanical fatigue and creep; 5 - Lightweight – low density; 6 - High hardness and wear resistance; 7 - Excellent thermal shock resistance; 8 - Low thermal expansion; 9 - Electrical insulator; 10 - Good antioxidant properties; 11 - Good resistance to chemical corrosion.
