Mirrow Polishing high precision Zirconia Ceramic plate
Description:
Zirconium oxide is employed to an increasing extent, on the grounds of its useful characteristics: high rupture strength, comparable thermal expansion to cast iron, exceptionally high flexural and tensile strength, high resistance to wear and abrasion, and low thermal conductivity. Moreover, this material is a conductor of oxygen ions, and possesses excellent tribological properties.
The highest surface roughness that can be achieved on ceramic surface is Ra0.1, which is equivalent to a mirror-like polished finish.
