First, the shortcomings of barium zirconate ceramics
Barium zirconate ceramics is a kind of ceramic material with high strength, high toughness and high environmental stability, which is widely used, but it still has some shortcomings in some aspects:
- easy to crack
Barium zirconate ceramics are prone to cracking during preparation and use, especially during sintering. - Difficult to process
It is difficult to process barium zirconate ceramics, which generally requires special equipment and technology, and the processing cost is high. - Large chromatic aberration
In the process of use, barium zirconate ceramics are easily affected by temperature and environment, and the color difference is large.
Second, the improvement method
In order to overcome the shortcomings of barium zirconate ceramics, the following measures need to be taken:
- Optimize the sintering process
By optimizing the sintering process, the stress in the sintering process is reduced and the cracking rate of barium zirconate ceramics is reduced. - Improve the processing technology
Appropriate processing technology is adopted to reduce the processing cost and improve the processing efficiency, such as CAD/CAM aided design and numerical control processing.
Step 3: Optimize the formula
By adjusting the chemical formula of barium zirconate ceramics, its tensile strength, hardness and thermal stability are improved. - Improve the stability of materials
Proper stabilizer can improve the stability of barium zirconate ceramics, reduce its sensitivity to temperature and environmental changes, and reduce color difference.
Conclusion
Barium zirconate ceramics is a kind of material with excellent properties, but there are still some shortcomings in its use. By adopting the above measures to improve its properties, the application scope and economic benefits of barium zirconate ceramics can be further improved.
