    High-Purity Ceramic Nozzles For High-End Industrial Applications Near-Full Density Ultra-High Strength And Extended Service Life

    High-Purity Ceramic Nozzles For High-End Industrial Applications Near-Full Density Ultra-High Strength And Extended Service Life


    This product is manufactured using 99.5% high-purity silicon nitride (Si₃N₄) powder through 200MPa isostatic pressing and 1800°C gas pressure sintering (GPS) processes. The manufacturing technology ensures an ultra-dense microstructure with porosity <0.5%, making it an ideal choice for high-end industrial applications.

    Primary Applications

    • Aviation industry: Fuel injection systems for aircraft engines

    • Energy equipment: Combustion chamber nozzles for gas turbines

    • Automotive manufacturing: High-pressure common rail injection systems

    • Industrial spraying: HVOF (High-Velocity Oxygen Fuel) spraying

    • 3D printing: Metal powder atomization systems

    Key Advantages

    ✓ Ultimate density: Near-full density achieved (relative density ≥99.5%)
    ✓ Ultra-high strength: Flexural strength ≥700MPa
    ✓ Exceptional temperature resistance: Continuous use at 1600°C
    ✓ Superior thermal shock resistance: Withstands 1000°C thermal gradients
    ✓ Extended service life: 2-3 times longer than conventional sintering products

    Manufacturing Process

    1. Material preparation: Nano-grade Si₃N₄ powder (D50≤0.5μm) + sintering additives

    2. Pre-forming: Cold Isostatic Pressing (CIP) 200MPa for 30min

    3. Gas pressure sintering: 1800°C nitrogen atmosphere, 4h dwell time

    4. Precision machining: 5-axis CNC precision grinding

    5. Quality inspection: X-ray density testing + ultrasonic flaw detection

    6. Performance testing: Three-point bending test + thermal shock test

    Usage Guidelines

    ⚠️ Installation: Use ceramic-specific installation tools
    ⚠️ Pressure limit: Operating pressure ≤80MPa
    ⚠️ Temperature control: Heating rate ≤5°C/min (above 1000°C)
    ⚠️ Media requirements: Avoid HF and molten alkali metals

    Service Commitment

    • Technical support: Free CFD analysis provided

    • Customization: Special bore sizes and angles available

    • After-sales response: 24-hour technical consultation

    FAQ

    Q: Advantages of GPS vs conventional sintering?
    A: 2-3% higher density, 20%+ strength improvement, 2-3x longer lifespan.

    Q: Maximum machinable bore size?
    A: Standard max 50mm, special process up to 80mm.

    Q: Performance in reducing atmospheres?
    A: Stable below 1600°C, recommended with protective atmosphere.
