Description
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.
Technical Data Sheet: Calcined Alumina Grades
The following table outlines key specifications for our standard grades. Custom formulations are available upon request.
