Application of Zirconia ceramic

Zirconia ceramic (ZrO₂ ceramic), valued for its high toughness, thermal shock resistance, and high-temperature stability, is widely applied in automotive, medical, electronics, and industrial fields. Its specific applications are as follows:

1. Automotive Industry (Core Application Field)

• Exhaust Gas Sensors: Yttria-stabilized zirconia (YSZ) is the key electrolyte material for automotive oxygen sensors and NOₓ sensors. It can accurately detect the oxygen concentration in exhaust gas at high temperatures (300–900°C), helping the engine optimize the air-fuel ratio and reduce emissions.

• Electric Drive System Components: Used to manufacture ceramic bearings (for high-speed motors of new energy vehicles) and motor insulation parts. Its high toughness and wear resistance ensure long-term stable operation of the motor, and it can withstand the temperature fluctuations of the drive system.

• Engine & Thermal Management Parts: Applied in engine valve seats, heat shields, and turbocharger components. Its excellent thermal shock resistance (withstands ≥500°C temperature changes) and high-temperature stability (long-term use up to 1200°C) adapt to the harsh thermal environment of the engine.

• Brake System Accessories: As a composite material component in ceramic brake pads, it enhances the wear resistance and high-temperature resistance of the brake pad, reducing brake noise and extending the service life.

2. Medical Field

• Dental Restorations: The most mainstream application—used to make all-zirconia crowns, bridges, and implants. It has natural tooth-like translucency, non-toxicity, and excellent biocompatibility (no allergic reaction to human tissues), and its strength is sufficient to withstand chewing forces.

• Surgical Instruments & Implants: Manufactures high-precision surgical scalpel blades (with sharp edges and wear resistance) and orthopedic implants (e.g., artificial joint femoral heads). Its corrosion resistance (resistant to body fluids) and biocompatibility avoid rejection reactions.

3. Electronics & Electrical Field

• Electronic Substrates & Insulators: Used as high-frequency circuit substrates and insulator parts for power electronic devices (e.g., IGBT modules). Its good electrical insulation (volume resistivity ≥10¹⁴ Ω·cm) and thermal conductivity help dissipate heat from electronic components and ensure stable signal transmission.

• Semiconductor Processing Parts: Makes quartz boat liners and wafer carriers for semiconductor factories. It is resistant to high temperatures (withstands 1200°C annealing processes) and corrosion (resistant to acid-base cleaning agents), avoiding contamination of wafers.

4. Industrial & Daily-Use Fields

• Wear-Resistant Components: Produces mechanical seals, pump impellers, and ceramic nozzles (for spraying equipment). Its high hardness (Mohs hardness 8.5) and wear resistance extend the service life of parts in harsh working conditions (e.g., slurry transportation, high-pressure spraying).

• Kitchenware & Decorations: Makes zirconia ceramic knives (sharp, no rust, no metal ion precipitation) and high-end decorative panels. It is non-toxic, easy to clean, and has a smooth surface, which is popular in daily life.
