Analysis of Advantages and Disadvantages of Zirconia Ceramics

Advantage

1、High hardness and wear resistance

Extremely high hardness (Mohs hardness of about 8.5), close to steel, not easily scratched or damaged during daily use, suitable for high-strength scenarios such as dental posterior tooth restoration and industrial cutting tools.

2、Corrosion resistance and chemical stability

It has strong corrosion resistance to various chemicals, stable performance, and is not easily corroded by substances such as acid and alkali.

3、Excellent biocompatibility

It does not release harmful substances, has low tissue irritation, is not prone to allergies or inflammation, and is suitable for medical fields such as dental implants and artificial joints.

Shortcoming

4、High brittleness risk

Although it has high strength, the material is relatively brittle and may break when subjected to sudden impact or excessive pressure. When using, it is necessary to avoid collisions with hard objects.

5、High processing cost

The material price is 5-8 times higher than that of metals, requiring specialized CAD/CAM cutting and high-temperature sintering equipment. The process is complex and time-consuming,

The overall cost is significantly higher than traditional materials.

6、Low temperature aging effects

The high toughness of materials relies on stabilizers, and their stability gradually decreases over time or in high-temperature environments, which may lead to weakened performance and requires regular inspection.
