Product Description

Alpha Alumina (α-Al₂O₃) is the most thermodynamically stable phase of alumina, produced through high-temperature calcination processes. It features a well-defined crystal structure, high hardness, and excellent resistance to heat and chemical corrosion.

With controlled particle size distribution and high purity, α-alumina is widely used as a key raw material in advanced ceramics, refractories, polishing applications, and functional materials. It ensures consistent performance in both industrial and high-end applications.

Different grades are available to meet various requirements in particle size, purity, and application performance.
