zirconia ceramics

Zirconium Oxide Ceramic

Zirconia ceramic is made of high purity zirconia powder as the main raw material, adding a certain amount of stabilizer (such as yttrium oxide, magnesium oxide, etc.), mixed evenly after forming, sintered at high temperature, to obtain a crystal phase stable ceramic structure. Zirconia ceramics have high temperature resistance, good thermal shock resistance, high hardness, good wear resistance and corrosion resistance, and very good toughness, so it is also known as "ceramic steel". It is widely applied in various fields, including mechanical engineering, petrochemical, electronic appliances, medical and biological industries, measuring instrument and meter, comprehensive performance is excellent.

Advanced Ceramic By Applications

Advanced ceramics play a pivotal role in various industries, offering a unique combination of exceptional mechanical, thermal, and electrical properties. Unlike traditional ceramics, advanced ceramics are engineered to deliver superior performance in demanding applications. These materials, often based on non-metallic compounds, exhibit high hardness, wear resistance, and corrosion resistance, making them indispensable in a wide range of industrial sectors.

Properties of ZrO2 Ceramic

Zirconia ceramics is one of the most widely used advanced industrial ceramics, in order to meet the needs of different fields, various type stabilizer is added into raw material, so the performance has been comprehensively promoted and improved.

 

1. Corrosion resistance

The zirconia material has good corrosion resistance, it can be in contact with various acids, alkalis, salt water and other chemical agents, without the risk of failure caused by corrosion, and does not pollute the contacted liquid.

 

2. High temperature resistance

The normal use temperature of the zirconia ceramic can reach higher than 2400℃, available for the requirements of high temperature environment.

 

3. Good wear resistance

Zirconia material has high hardness and good wear resistance, so the service life is long.

 

4. Good toughness and high strength 

Toughness of zirconia ceramic is the highest among ceramic material, even better than some common used metals, also the strength is high.

 

5. Excellent biocompatibility

Zirconia has excellent biocompatibility, it is harmless and non-toxic, and can be used in devices that may have direct or indirect contact with the human body.

 

6. High surface finish

Surface finish is very high after polishing, friction is very small.

Q:How does Zirconia ceramic perform under extreme temperatures?
A:Zirconia ceramic has melting point of 2700℃ and excels in high-temperature environments, maintaining its mechanical strength and structural integrity up to 2100℃, and the performance may degrade beyond 2400℃. Overall, Zirconia ceramic is a reliable choice for high-temperature applications.

 

Q:What is the chemical corrosion resistance of Zirconia ceramic?
A:Zirconia ceramic is highly resistant to most acids, alkalis, and organic solvents, making it suitable for use in harsh chemical environments. However, it can be affected by hydrofluoric acid, so caution is needed in those conditions. Its excellent resistance to oxidizers further enhances its performance in corrosive environments.

 

Q:How is Zirconia ceramic used in biomedical applications, and what is its biocompatibility?
A:Zirconia ceramic is widely used in dental and orthopedic implants due to its high biocompatibility, strength, and toughness. It does not trigger immune responses or allergies and offers excellent durability in the body, making it an ideal material for long-term implants.

 

Q:What are the electrical insulation properties of Zirconia ceramic?
A:Zirconia ceramic offers excellent electrical insulation, with a dielectric constant between 22 and 30 and a high resistivity typically ranging from 10^10 to 10^14 ohm·cm. This makes it suitable for high-frequency applications where stable insulation is required, such as in electronic components and insulators.

 

Q:How does Zirconia ceramic perform in high-wear applications?
A:Zirconia ceramic is known for its high hardness (typically between 1200 and 1400 Vickers hardness) and superior wear resistance, making it ideal for use in bearings and other high-wear components. Its toughness and impact resistance far exceed that of traditional alumina ceramics, offering long-lasting performance in demanding environments.
