Ⅰ.Comprehensive Introduction to Zirconia Bushings
Zirconia bushings are industrial components made from zirconia ceramic material, possessing the following significant characteristics:
1. Physical Properties:
Density: 5.9-6.0 g/cm³.
Mohs Hardness: 8.8-9.0 (second only to diamond).
Coefficient of Thermal Expansion: 10×10⁻⁶/℃.
Thermal Conductivity: 2.5 W/m·K.
Operating Temperature: ≤1050℃ (up to 2400℃ with special treatment).
2. Mechanical Properties:
Compressive strength: 2500 MPa.
Flexural strength: 1200 MPa.
High toughness (compared to traditional ceramics).
3. Chemical Properties:
Excellent chemical inertness and resistance to corrosion from various chemicals.
Superhydrophobic surface (after special treatment), possessing self-cleaning and antibacterial properties.
Resistant to molten metal erosion.
Ⅰ.Application areas
Thanks to their excellent properties, zirconia bushings are widely used in various industrial fields:
Application areas | use | Advantages demonstrated |
