Premium Calcined Alumina for Fine Ceramics
High-performance calcined alumina featuring high alpha phase content (>95%), low sodium (<0.08%), and controlled particle size for die pressing, isostatic pressing and other ceramic forming processes.
High-Purity Calcined Alumina for Demanding Fine Ceramic Applications
Our premium calcined alumina is engineered for manufacturers of high-performance technical ceramics. Produced in a tunnel kiln under strict thermal controls, it delivers a consistent and reliable foundation for components where purity, microstructure, and sintering performance are critical.
Core Product Advantages
  • High Alpha Phase Content (>95%): Ensures optimal sintering behavior and final ceramic density, leading to superior mechanical and thermal properties.
  • Low Alkali Content (Na₂O ≤ 0.08%): Minimizes the risk of glass phase formation and grain growth anomalies during firing, resulting in a more predictable and stable microstructure.
  • Exceptional Chemical Purity (Al₂O₃ ≥ 99.7%): Reduces impurities that can compromise the performance, color, and electrical insulation of the final ceramic product.
  • Precisely Controlled Particle Size: Multiple grades available with tightly controlled particle and crystal sizes, allowing for tailored powder packing and shrinkage management.

Applications in Advanced Ceramics
Our calcined alumina is the material of choice for a wide range of technical ceramic forming processes and end-products:
Forming Processes
  • Dry Pressing & Isostatic Pressing: Excellent flowability and compaction for high-density green bodies.
  • Hot Pressure Casting: Suitable for complex shapes and high-volume production.
End-Use Components
  • Structural Ceramics: High-wear components, liners, and nozzles
  • Ceramic Seals: Mechanical face seals requiring high hardness and corrosion resistance
  • Electronic Substrates & Insulators: Where high purity ensures excellent electrical properties
  • High-Quality Alumina Grinding Media & Balls: Used as raw material for granulation in premium alumina grinding bodies
