Introduction to Porous Zirconia Ceramic Products
Porous zirconia ceramic is a high-performance ceramic material primarily composed of zirconium dioxide (ZrO₂). It is typically white at room temperature and contains trace amounts of hafnium dioxide (HfO₂) and the stabilizer yttrium oxide (Y₂O₃). Its characteristics include:
1. High melting point: Reaching 2715℃, it can withstand high-temperature environments up to 1500°C.
2. High strength: It possesses extremely high mechanical strength and toughness, with a bending strength of up to 1100 MPa.
3. Wear resistance: The surface is hard, with a Mohs hardness of 7.5 or higher, making it resistant to wear.
4. Chemical stability: It exhibits stability in acidic, alkaline, and organic solvent environments.
5. Permeability: The porous structure provides it with certain ventilation and thermal insulation properties.
