Zirconium oxide ceramic nozzles are industrial ceramic components manufactured from high-performance zirconia (ZrO2) material. Their widespread application across numerous fields is primarily attributable to their exceptional material properties.
Core Features
1. Exceptional Wear Resistance
This is the most prominent advantage of zirconia nozzles. Their high hardness provides wear resistance far exceeding that of traditional metal or plastic nozzles. When handling slurries containing hard particles, powders, or operating under high-pressure conditions, they exhibit an extremely long service life. They maintain stable internal bore dimensions and shape over extended periods, ensuring consistent machining precision.
2. Exceptional Corrosion Resistance
Zirconia ceramic is a chemically stable material resistant to corrosion from most acids, alkalis, and chemical solvents. This makes it ideal for use in corrosive environments such as chemical processing, electroplating, and spray coating applications.
3. High Strength and Toughness
Through specialized toughening techniques—such as incorporating yttria as a stabilizer to form “yttria-stabilized zirconia”—zirconia ceramics exhibit one of the highest fracture toughnesses among ceramic materials. It resists brittle fracture and demonstrates excellent resistance to mechanical impact.
4. High-Temperature Resistance
Zirconia possesses an exceptionally high melting point (approx. 2700°C), maintaining its properties without deformation or softening in high-temperature environments. This makes it suitable for applications such as high-temperature spraying and burners.
5. Non-Wetting Properties and Smooth Surface
The inner wall of the nozzle can be machined to an extremely smooth finish that resists liquid adhesion. This helps minimize clogging, ensures unobstructed fluid flow, and produces a stable, uniform spray pattern.
Main Application Areas
Based on the above advantages, zirconia nozzles are commonly used in:
1. Sandblasting and rust removal equipment
As nozzles for sandblasting machines, their wear resistance is several to dozens of times greater than that of tungsten steel nozzles.
2. High-pressure waterjet cutting
Used in ultra-high-pressure waterjet equipment (up to 4000 bar or higher), serving as a core wear-prone component.
3. Coating Industry
Ensures uniform coating application and wear resistance in processes like electrostatic spraying, powder coating, and paint spraying.
4. Electronics industry
Used in processes like chip and wafer cleaning to spray ultra-pure water or chemical reagents.
5. Chemical and environmental protection
Employed in spray drying towers, exhaust gas scrubbers, dust removal equipment, etc.
6. Flame spraying
As nozzles for spray guns, they withstand the erosion of high-temperature molten materials.
