Silicon Nitride Ceramic: Industrial Silicon Nitride Ceramic Ring
Silicon nitride ceramics (Si3N4) have excellent performance, but poor mechanical properties and are easily oxidized at high temperatures.
Features:
1. Si3N4 has a low coefficient of thermal expansion and high thermal conductivity, resulting in excellent thermal shock resistance. Hot-pressed silicon nitride will not crack even when heated to 1000°C and placed in cold water.
2. Silicon nitride ceramic is an inorganic material that does not shrink during the sintering process. Silicon nitride is extremely strong, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, and high-temperature resistance.
3. At moderate temperatures, Si3N4 exhibits high strength and impact resistance. However, above 1200°C, it degrades over time, resulting in a decrease in strength.
4. Fatigue damage is more likely to occur above 1450°C, so the operating temperature of…
