Product Description

White Corundum Alpha Aluminum Oxide Powder Engineering Ceramics


1. Introduction

    White corundum is made from industrial alumina powder, which is melted in arc furnace at a high temperature of more than 2000 degrees and then cooled. After grinding and shaping, magnetic separation of iron, particle size screening into different products.

    White Fused Alumina is a pure, clear Fused Alumina, which makes the whitest vitrified wheels possible with low soda and silica content. This is the most friable aluminum oxide. Due to its high purity and large crystal size, its crystals fracture comparatively swiftly and constantly cutting crystals to small pieces.


2. Attribute

1.Chemical composition: min99.4% Al2O3

2.Density: 3.95g/cm³


Grits Grain size (UM)

3. Advantages

1. The original production, sufficient inventory

2. High hardness, angular shape

3. Lower risk of pollution

4. Intellectual property protection

5. Raw manufacturers have complete control over the production process, which means they can ensure the quality of their products and respond quickly to any issues or changes in demand


4. Applications

1. White corundum ceramic ball is a kind of anti-corrosion and anti-abrasion ceramic products, widely used in Engineering Ceramics.

2. White corundum can be used to prepare high-precision capacitors, piezoelectric ceramics and other electronic ceramic products.

3. White corundum can be used for bonded and coated abrasives.
