Combining Metal Toughness With Ceramic Hardness Zirconia Ceramics For High-Performance

Product Description

This product is precision-engineered from high-performance Zirconia (ZrO2) ceramic material, specifically designed to withstand extreme and demanding operating environments. Its unique polycrystalline structure grants it unparalleled comprehensive properties, combining the toughness of metal with the hardness of traditional ceramics. It is an ideal material for manufacturing critical components such as high-precision bearing rings, advanced insulating rings, and corrosion-resistant structural supports. Whether your equipment faces high-speed wear, chemical corrosion, or high-temperature challenges, this product provides a durable and stable solution.

Key Advantages

• Ultra-High Strength & Toughness: Flexural strength exceeding 1000 MPa. Its unique phase transformation toughening mechanism effectively prevents crack propagation, fundamentally changing the perception of traditional ceramics being brittle.

• Exceptional Wear Resistance: Hardness second only to diamond, with a low friction coefficient. It performs excellently under unlubricated or poorly lubricated conditions, with a service life dozens of times longer than metal parts.

• Excellent Temperature Resistance & Insulation: Withstands temperatures up to 1500°C. Its thermal expansion coefficient is close to that of metal, facilitating easy assembly with metal components, while also offering excellent thermal insulation.

• Outstanding Corrosion Resistance & Electrical Insulation: Resists corrosion from most acids, alkalis, and organic solvents, while maintaining stable high insulation resistance, ensuring safe operation in complex electromagnetic environments.

Primary Applications

• Precision Machinery: High-speed spindle bearing rings, balls, guides, support members for measuring instruments.

• Electronic Equipment: Insulating rings in semiconductor manufacturing equipment, vacuum chucks, RF windows.

• Chemical & Medical Industries: Pump and valve seals, reactor linings, medical implants, and surgical tools.

• High-Temperature Environments: Furnace supports, thermocouple protection tubes, thermal insulation components for aerospace engine applications.
