Material

Zirconia Ceramic (ZrO2)

Zirconia ceramic is a new type of inorganic non-metallic material, the common zirconia material included yttrium stabilized zirconia(YSZ) and magnesium stabilized zirconia ceramics(MgO-PSZ).
Zirconia ceramics have excellent chemical and physical properties, widely used in industrial production.

Application

1. Medical and Dental

Artificial joints, such as hip and knee replacement prostheses, utilize their high hardness, wear resistance, and biocompatibility.

Dental restoration, surgical instruments such as surgical blades and other precision tools.

2Structural components 

Such as plungers, valve core balls, guide blocks, industrial knives, and shafts.

Zirconia ceramics are widely used in the field of structural ceramics due to their excellent material properties. Firstly, its high toughness makes it less prone to fracture when subjected to impact or stress, making it suitable for structural components in high load and dynamic environments, such as mechanical bearings and medical implants.

3. Automotive industry:

Engine components such as oxygen sensors, spark plug insulators, high-performance brake pads, turbocharger rotors.

4. Chemical industry:

Pumps, valves, and other corrosion-resistant components: These devices are often exposed to strong acidic and alkaline environments, and zirconia ceramics can effectively resist chemical corrosion. It can also be used for lithium battery liquid filling pumps, cutters, emulsion high-pressure pump plungers.
