Silicon Nitride Complex Parts: The Ultimate Solution for Extreme Environments

Engineers battling thermal shock, corrosion, and wear in harsh environments now turn to silicon nitride (Si₃N₄) complex parts. These custom-engineered components deliver unmatched performance where traditional materials fail.

1.Key application areas

Aerospace:

• Rocket nozzle insulators (withstands 1,800°C re-entry heat)
• Satellite thrusters (50% weight reduction vs. Inconel)

✅ Semiconductor:

• Plasma etch rings (zero particle contamination, 99.999% purity)
• Wafer handling claws (anti-static, <0.01μm wear/year)

✅ Energy:

• Hydrogen pump rotors (0% hydrogen embrittlement at 700°C)
• Nuclear reactor guides (radiation-resistant, 30-year lifespan)
