Product Feature

1. The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency. 

2. High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.

3. The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter. 

4. Low oil absorption especially for water-based paint. 

5. Neutral property with PH value around 7-8. 

6. High whiteness. It doesn't affect the color of paints or coatings adding Al2O3 powder. 

7. Resistant to most corrosive alkali and acid. It doesn't dissolve in water. 

8. Resistant to high temperature up to 1900 °C. 9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.

Application Scenarios

1. Grinding and Polishing: White fused alumina grits are widely used in grinding and polishing applications. They are used in the manufacturing of abrasive wheels, belts, and discs for precision grinding of metals, ceramics, and composites. The sharp and angular grains provide efficient cutting action and consistent surface finishes.

2. Surface Preparation: White fused alumina grits and sand are commonly used for surface preparation in industries such as foundries, metal fabrication, and shipbuilding. They are suitable for removing scale, rust, paint, and other surface contaminants from metal substrates, providing a clean and prepared surface for subsequent coating or bonding processes.

3. Refractories: Due to its high melting point and excellent thermal stability, white fused alumina is extensively used in the production of high-quality refractory products. It is used as a raw material to manufacture firebricks, refractory castables, and other shaped or unshaped refractory products. These are widely utilized in high-temperature industries such as steel, cement, and glass manufacturing.

4. Precision Casting: White fused alumina powder is used as a precision casting material. It is mixed with a binder and applied in the production of investment casting molds or cores, resulting in high-dimensional accuracy, smooth surfaces, and improved casting quality.

5. Abrasive Blasting: White fused alumina grits and sand are utilized in abrasive blasting operations. They are commonly used for surface cleaning, etching, and preparation in industries such as metal fabrication, automotive, and aerospace. The sharp and hard grains effectively remove rust, paint, scale, and other contaminants from surfaces without causing damage.

6. Superabrasives: In some applications, white fused alumina is used as a superabrasive material, either alone or as a component in bonded or coated abrasive tools. It can be used for precision grinding of hard and brittle materials like high-speed steels, tool steels, and ceramics, where high material removal rates and superior surface finishes are required.

7. Ceramics and Tiles: White fused alumina powder is used as an additive in the production of ceramics and tiles. It improves the strength, hardness, and thermal shock resistance of the final products.
