Fused zirconia

Fused Zirconia is a high-performance, synthetic material composed primarily of zirconium dioxide (ZrO₂) produced by melting zircon sand at extremely high temperatures. This process yields a dense, crystalline material with excellent mechanical, thermal, and chemical properties. Fused Zirconia is used in various demanding applications, including refractory materials, abrasives, and advanced ceramics, due to its superior hardness, toughness, and thermal stability.

  • Product Category: Abrasive & Material
  • Key Features:
  • High Thermal Stability: Capable of withstanding high temperatures without significant degradation, making it ideal for use in refractory applications and high-temperature processes.
  • Chemical Resistance:Resistant to most acids and bases, providing durability and stability in harsh chemical environments.
  • Low Thermal Expansion: Exhibits minimal thermal expansion, reducing the risk of defects in castings and enhancing the dimensional accuracy of materials.
  • High Purity: Composed predominantly of forsterite, ensuring consistent quality and performance.
Applications:

Refractory Materials: Used in the production of refractory bricks, linings, and coatings for furnaces, kilns, and reactors to enhance thermal stability and resistance to thermal shock.

Abrasives: Employed as an abrasive in grinding wheels, cutting tools, and other abrasive materials due to its hardness and wear resistance.

Advanced Ceramics: Utilized in the manufacture of advanced ceramic components and devices, including those used in electronics, aerospace, and industrial applications.

Coatings: Applied as a coating material to improve the performance and longevity of components exposed to high temperatures or corrosive environments.

Catalysts: Used in catalytic processes where its stability and chemical resistance contribute to improved performance and efficiency.
