High Temperature Stability: Can operate stably at high temperatures up to 1600℃, suitable for special environments.
Superior Wear Resistance: The aperture expansion is less than 0.5% after 800 hours of molten steel jetting.
Chemical Inertness: Resistant to all inorganic and organic acids except hydrofluoric acid and concentrated NaOH.
Mechanical Strength: Compressive strength reaches 2500-3447 MPa, and its lifespan is 16 times longer than that of metal materials.
Product Introduction of Silicon Nitride Ceramic Single-Hole Nozzles:
Silicon nitride ceramic single-hole nozzles are special industrial nozzles manufactured from silicon nitride (Si₃N₄) material. They possess ultra-high hardness, excellent high-temperature resistance, and superior corrosion resistance. Their microstructure is polycrystalline, composed of many microcrystals, and the grain boundary structure significantly influences their performance. Compared to materials such as zirconia, silicon nitride ceramics exhibit superior wear resistance and erosion resistance, with a wear rate of only 0.1% under the same testing conditions.
Application Fields
1. Aerospace: Combustion chamber nozzles, temperature control accuracy ±5℃.
2. Metallurgical industry: High-temperature components such as molten steel treatment and aluminum electrolytic cell linings.
3. Chemical equipment: Corrosion-resistant ball valves, pump bodies, filters, etc.
4. Electronics manufacturing: Semiconductor CVD equipment, resistant to Cl₂ plasma corrosion.
5. Food and beverage: Liquid mixing and dispersion, long-term stable use.
