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.

Zirconia Ceramic By Shapes

As our important product, ATCERA can produce various zirconia ceramic tubes, balls, rods, measurement instrument, plates, and mechnical parts. To ensure product performance, we select high purity and granularity homogenuous powder, and stabilizer powder, apply the most appropriate forming method and sintering temperature, to form dense and uniform ceramic structure,  then advanced machining processes are used to get dimension with high accuracy and good surface finish. If you have any product request, or need technical support, please do not hesitate to contact us.

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.
