Zirconia Ceramics

Zirconia used for wear resistant parts, heat resistant parts

Main Characteristics: High Mechanical Strength Good Wear and Heat Resistance.

Main Applications: Wear-resistant, heat-resistant parts, such as sand mill accessories.

Zirconia (ZrO2) is the material with the highest mechanical strength and toughness in precision ceramics.and the thermal expansion rate is close to metal, and it is easier to combine with metal, is also a special feature of zirconia ceramics.

    Zirconia ceramics are the most powerful materials in oxide ceramics. With excellent impact strength, high wear and corrosion resistance, and low thermal conductivity, it has been used in a wide variety of applications, and continuous and permanent optimization ensures that the material always meets current requirements.

    Shortcomings, such as brittleness, are also eliminated on an ongoing basis. In high-performance ceramics aspect, the high-tech material- zirconia ceramics has set entirely new standards and priorities.this means that designers have a material to work with that allows positive properties to come out even when using a floral filament structure. In addition, the ceramic has a good handfeel, good biocompatibility, and high corrosion resistance and durability. designers also appreciate its beautiful appearance.
