Durable Ceramic Nozzles Offering Superior Thermal Shock Resistance and Ultra Dense Microstructure for Industrial Spraying
Durable Ceramic Nozzles Offering Superior Thermal Shock Resistance and Ultra Dense Microstructure for Industrial Spraying
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
