    High-Temperature Ceramic Nozzles With Rapid Temperature Adaptation For Extreme Operating Conditions

    High-Temperature Ceramic Nozzles With Rapid Temperature Adaptation For Extreme Operating Conditions


    Manufactured from 99.5% high-purity silicon nitride (Si₃N₄) through specialized formulation design and gas pressure sintering technology, this product demonstrates exceptional thermal shock resistance. Capable of withstanding sudden temperature variations up to 1200°C without cracking, making it ideal for extreme operating conditions with rapid temperature fluctuations.

    Primary Applications

    • Aircraft engines: Fuel injection systems for combustion chambers

    • Steel metallurgy: Secondary cooling nozzles for continuous casters

    • Glass manufacturing: Annealing lehr jet systems for float glass

    • Chemical equipment: High-temperature reactor injection devices

    • Heat treatment furnaces: Rapid quenching cooling systems

    Thermal Shock Advantages

    ✓ Exceptional ΔT resistance: Withstands 1200°C thermal shock
    ✓ Rapid temperature adaptation: Permits 20°C/s heating/cooling rates
    ✓ High-temperature stability: Maintains structural integrity at 1600°C
    ✓ Thermal fatigue resistance: >95% strength retention after 1000 cycles
    ✓ Quenching-proof: 100% pass rate in water quenching tests
