Activated Alumina 1302-74-5

AL2O3 alumina polishing powder is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness, and sharp in shape.

Calcined Alumina is the basic raw material for heat-resistance and corrosion-resistance products, These make sure it has the advantages as follows: less trash, high transfer rate, stable contraction, and great variety of goods. The shape is fine sand or powdery with white color, As its equal particle sizes and dispersing easily, it has a good sinterability.

Key Features:

1.High Hardness: Alumina exhibits exceptional hardness, making it suitable for various industrial applications where abrasion resistance and scratch resistance are essential, particularly in grinding, polishing, and cutting tools. 
2.High Purity: Industrial-grade alumina typically boasts high purity levels, making it suitable for applications requiring exceptionally pure materials, such as electronic material preparation. 
3.Precise Particle Size Control: High-quality alumina usually comes with precisely controlled particle sizes, which are critical for specific processes and applications. Alumina with different particle sizes can meet various requirements.
