What is the difference between 96 and 99 alumina?

96% alumina porcelain contains about 96% aluminum oxide, making it lower in purity and more cost-effective than 99% alumina. It offers good thermal conductivity and decent electrical insulation, suitable for wear-resistant parts and general ceramics. In contrast, 99% alumina has higher purity, providing superior mechanical strength, thermal stability, and electrical insulation, making it ideal for high-performance applications in electronics and specialized ceramics. The choice between them depends on the specific requirements and budget of the application.

96% Alumina Porcelain

• Purity: Contains approximately 96% aluminum oxide, making it lower in purity compared to 99% alumina.
• Cost-Effectiveness: Generally more affordable than 99% alumina, making it a popular choice for various applications.
• Properties:
  • Thermal Conductivity: Offers good thermal conductivity, suitable for applications where heat transfer is important.
  • Electrical Insulation: Provides decent electrical insulation, making it useful in electrical components.
• Applications: Commonly used in wear-resistant parts, cutting tools, and general ceramics where extreme purity is not critical.

99% Alumina

• Purity: Composed of about 99% aluminum oxide, offering higher purity and performance.
• Properties:
  • Higher Strength: Enhanced mechanical strength and thermal stability.
  • Superior Insulation: Better electrical insulating properties, ideal for advanced applications.
• Applications: Used in high-performance ceramics, electronics, and environments requiring extreme durability.

Summary

In summary, while 96% alumina porcelain is cost-effective and versatile, 99% alumina offers superior performance in specialized applications. The choice between the two depends on the specific requirements of the intended application.
