Zirconia ceramics have occupied a place in many industrial fields due to their excellent properties. First of all, it has ultra-high hardness and flexural strength, which is significantly better than traditional metal and ceramic materials. Its Mohs hardness can reach 1200 to 1400 HV, and the flexural strength can also reach 900 to 1200 MPa, which makes it particularly outstanding in applications with extremely high strength requirements.
Secondly, the wear resistance and corrosion resistance of zirconia ceramics are also excellent. Its high hardness and dense structure give it excellent wear resistance, and it can maintain stable operation for a long time in harsh friction and wear environments. At the same time, it has strong resistance to the erosion of chemical media such as acid and alkali, and has good corrosion resistance.
In addition, zirconia ceramics exhibit extremely high stability at high temperatures. It has a high melting point and can be used for a long time in a high-temperature environment of more than 2000 meters, which makes it an important application value in high-temperature applications.
In the field of electronics, zirconia ceramics also perform well, it is an excellent insulating material, with low conductivity and dielectric constant, even under high temperature and high frequency conditions, can maintain good insulation properties, very suitable for electronic devices and high-voltage equipment.
It is worth mentioning that zirconia ceramics also have good biocompatibility and do not cause allergies or rejections, so they have a wide range of applications in the dental and biomedical fields, such as making dentures, artificial joints and bone repair materials.
Finally, the dimensional stability of zirconia ceramics is also a highlight, with low thermal expansion coefficient and excellent dimensional stability allowing it to maintain high accuracy and stability, especially suitable for applications that require high precision and stability.
To sum up, zirconia ceramics have a wide range of application prospects in mechanical engineering, electronics, medical and many other fields due to their high hardness, high strength, excellent wear resistance, corrosion resistance, high temperature stability, excellent insulation properties, biocompatibility and high maintenance accuracy.
