Zirconia Sheet，Zirconia Ceramic Sheet
Zirconia sheet is a high-performance ceramic material made of zirconium oxide (ZrO2). It has the characteristics of high hardness, high strength, high temperature resistance, acid and alkali corrosion resistance and good biocompatibility.

Zirconia Sheet Toughening
Our zirconium oxide sheets can be doped with other compounds to increase toughness. The most commonly used toughening techniques are doping with rare earth oxides and composite materials.
Doping with rare earth elements: The method we often use is doping with yttrium oxide to obtain partially stabilized zirconia (PSZ) and fully stabilized zirconia (FSZ), which can greatly improve the toughness of zirconia sheets.
Composite materials: The technology we most commonly use is to compound zirconium oxide with alumina or silicon carbide to obtain zirconium oxide toughened alumina (ZTA), which will greatly improve the material toughness and fracture resistance of the ceramic!

Performance Parameters of Zirconia Sheets
Mechanical properties: Our zirconium oxide sheets have a compressive strength of more than 2000MPa and are more ductile than ordinary ceramics, which can help you overcome the difficulties encountered in high-intensity environments.
Thermal properties: Our zirconia sheets have extremely high heat resistance and can withstand high temperatures of 1600°C. The mechanical and chemical properties remain stable at high temperatures, and the service life is longer. Zirconia sheets have low thermal conductivity and can also be used for thermal insulation applications. Our superior zirconia ceramic sheets are your best choice!
Electrical properties: Zirconia sheets have excellent electrical insulation properties and can be used for LED substrates, sensor substrates, etc. They are very superior ceramic materials.

Zirconia Sheet Related Processes
Molding: Slurry injection molding, isostatic pressing.
Surface roughness: There are a variety of surface treatments for you to choose.
- Ra0.2μm: The surface finish is optimal, very suitable for your high finish and low friction applications, such as high-precision electronic substrates.
- Ra≤0.80μm: It adopts cold rolling treatment, and the surface finish is moderate. You can use it in general electronic machinery fields.
- Ra≤1.20μm: Cold rolled and ground, with a certain degree of smoothness, but the surface finish is not high.
- Ra≤1.60μm: Cold rolled pickling treatment, matte surface, suitable for applications with low requirements for surface reflection.
Processing accuracy: We can achieve a processing accuracy of ±0.001mm for high-precision zirconia sheets and a tolerance of ±0.02mm for non-precision products, ensuring that your needs are met.
