Basic Introduction to Zirconia Ceramic Positioning Blocks and Irregularly Shaped Parts
Zirconia ceramic is a high-performance engineering ceramic material with the following significant characteristics:
1. High hardness and wear resistance: Vickers hardness reaches 11.5 GPa, far exceeding that of general ceramic materials, and can withstand considerable external forces without easily wearing down.
2. Excellent heat resistance: The melting point is as high as 2850℃, with good thermal stability, and it is not easily deformed or cracked in high-temperature environments.
3. Chemical stability: It has good corrosion resistance and can maintain stable performance in chemical media such as acids and bases.
4. Mechanical strength: Compressive strength reaches 2100 MPa, bending strength is 800 MPa, and fracture toughness is 8.0 MPam1/2.
5. Electrical insulation: The resistivity is as high as 10⁸ Ω·m, making it an excellent insulating material.
