Ground

Hindalco offers fine ground and super ground alumina with unique particle distributions and different chemical properties. It is available in various grades with different levels of soda content and defined specific surface area for meeting various applications.

Various grades series have a sodium oxide content typically ranging from 0.1% to 0.35%. The specific surface area (SSA) ranges from 0.9 to 1.2 m²/g, and the particle size distribution (PSD) D50 ranges from 3 to 5 microns.

Special grades series are designed with a wider particle size distribution, having a D50 between 4 and 5 microns.

Ground aluminas are used in applications such as glass/frits, Wear ceramics, refractories, brake pads and polishing. PG series of alumina are special grades exclusively for polishing applications. HCASG/HCAFG, ICSG/FG series of alumina are advanced grades with superior soda control and narrow particle distributions which helps meeting advanced ceramics and refractory applications.

The ground series of alumina enhances bulk density by better packing fraction and controlled pore size distribution. This elevates the performance such as thermal conductivity, electrical resistivity, thermal shock resistance, creep resistance, wear resistance, flexural and compressive strengths in ceramics and refractories. These properties are governed by the controlled particle size distribution and degree of crystallinity; with control on feedstock- Hindalco makes ground alumina versatile for various applications.
