Versatile Aluminium Oxide Al2O3 for Abrasives and Ceramics

Product Description

Product Description

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 for Grinding and Polishing
There are low sodium, medium sodium, ordinary active calcined alumina, mainly used for all kinds of products, substrates, metal polishing and so on, but also for aluminum-based refractory, industrial ceramics, inert catalyst raw materials.

Features: white powder or fine sand, with special crystal structure, uniform powder, suitable oil absorption rate, low impurity, high melting point, moderate hardness, strong self-sharpness, insoluble in water, insoluble in acid and alkali solution.

Application: widely used in grinding, stainless steel and other metal, substrate, jewelry, jade, stone and other polishing industry.

White Alumina Oxide Micro powder

The white alumina micro powder appears mostly pure white or slightly yellowish white, and is smelted from high-purity aluminum oxide through a special process. It has remarkable characteristics such as high hardness (Mohs hardness reaches 9), strong chemical stability, uniform particle size, good self-sharpening property, and high purity. 

 

In the fields of grinding and polishing, it can efficiently process materials like metals, glass, and ceramics.
In surface treatment, it is used for sandblasting and the production of grinding brushes and sandpapers. 
In the refractory materials industry, it serves as an important raw material for manufacturing refractory products and improving the performance of unshaped refractory materials.
In addition, it also plays a key role in the electronic industry, abrasive tool manufacturing and other fields, and has become an indispensable industrial material in many high-end manufacturing processes with its excellent performance.
