Zirconia porcelain blocks have excellent durability due to their excellent performance, which is reflected in the following aspects:
1. High strength and hardness
High strength: The bending strength of zirconia ceramics can reach more than 1000MPa, which makes it maintain good structural stability when it is subjected to large loads.
High hardness: Its hardness can usually reach 8-9 gpa, or even higher (such as Mohs hardness of about 8.5), which is one of the hardest materials available, ensuring excellent wear resistance. This high hardness makes the zirconia porcelain block less prone to wear during friction, thus prolongs its service life.
2. High temperature resistance
Zirconia ceramics have excellent high temperature resistance, melting point up to 2700℃. In high temperature environment, it can still maintain good dimensional stability and structural stability. In addition, zirconia ceramics also have good thermal shock resistance, even if suddenly cooled or heated at high temperatures, it will not easily crack and fracture.
3. Wear resistance
Due to its high hardness, zirconia porcelain blocks can maintain good wear resistance under the conditions of high speed movement and high load. In addition, zirconia ceramics also have good self-lubricating properties, even in the absence of lubricants can maintain a certain wear resistance.
4. Corrosion resistance
Zirconia ceramics have high stability to most acids, bases, salts and other chemicals, which makes it still maintain good performance and service life in chemical corrosive environments. This excellent corrosion resistance further enhances the durability of zirconia porcelain blocks.
5. Wide range of applications
Due to their excellent durability, zirconia porcelain blocks are widely used in many fields, such as dentistry (dental implants, crowns, etc.), electronics (semiconductor substrates, capacitors, etc.), aerospace (engine components, thermal barrier coatings, etc.) and industrial (cutting tools, wear components, etc.). These applications have very high requirements for the durability of materials, and zirconia porcelain blocks meet these needs with their excellent durability.
6. Service life
Under normal conditions of use, the service life of zirconia ceramics generally ranges from several years to ten years. The specific service life is also affected by many factors such as manufacturing process, application environment and use conditions. The service life of zirconia porcelain can be further extended by optimizing the manufacturing process, improving the application environment and reasonably designing the use conditions.
In summary, zirconia porcelain blocks have excellent durability because of their high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance and other excellent properties. This makes it widely used in many fields and has become one of the important materials in the field of modern industry and material science.
