Zirconia Ceramic Gear Product Introduction
Zirconia ceramic is a high-performance ceramic material primarily composed of zirconium dioxide (ZrO₂). At room temperature, it is mostly white and contains trace amounts of hafnium dioxide (HfO₂) and the stabilizer yttrium oxide (Y₂O₃). Its characteristics include:
1. High melting point: Reaching 2715℃, suitable for high-temperature environments.
2. High hardness: HV1250, exhibiting excellent wear resistance.
3. High toughness: Achieved through phase transformation toughening via crystal structure transformation (monoclinic phase, tetragonal phase, cubic phase).
4. Other characteristics: Corrosion resistance, non-magnetic and non-conductive, self-lubricating properties, and environmentally friendly.
Application Areas
1. Medical Field: Dental restorative materials (dental crowns, bridges), artificial joints and orthopedic implants, high-precision surgical instruments.
2. Industrial Machinery: Wear-resistant components (bearings, valves, pump bodies), cutting tools, oil extraction equipment.
3. Electronics and Semiconductors: Oxygen sensors, piezoelectric devices, integrated circuit substrates.
Supports custom specifications.
