What is White Fused Alumina?
White fused alumina, also known as white corundum, is an artificial abrasive made using an electric arc furnace process. It is a high-grade refractory material and a commonly used wear-resistant material. The main crystal phase of fused white alumina is α-Al2O3 (alpha alumina), and it is characterized by its pure white color. It appears as granules or white powder, with a microstructure of transparent crystals.

Characteristics, Properties, and Specifications of White Fused Alumina
- High Hardness: Rated 9.0 on the Mohs scale, White Fused Alumina is ideal for high-strength grinding and polishing applications.
- Good Toughness: Our F120-grade White Fused Alumina boasts a compressive strength of 100 KN/cm², ideal for demanding applications.
- Self-Sharpening: The angular crystal structure allows particles to maintain sharpness during grinding, making it a premium choice for abrasive grit and grit blasting.
- High Temperature & Thermal Shock Resistance: With low thermal conductivity and low thermal expansion, it performs well under extreme temperatures and shock conditions.
- Neutral pH Material: With a pH range of 7.0-8.0, White Fused Alumina offers good hydrophilicity and low oil absorption.
- Chemical Resistance: The high chemical inertness ensures long-lasting durability in both acidic and alkaline environments, ideal for industrial applications.

Production Process of White Fused Alumina
Produced by melting high-purity alumina powder at temperatures around 2250°C, White Fused Alumina undergoes a meticulous fusion process that ensures high purity and maximum hardness. This process differs from brown fused alumina production, as it minimizes sodium oxide (Na2O) to prevent the formation of β-Al2O3. This leads to a high-performance abrasive with exceptional fire resistance and chemical stability, making it suitable for high-tech applications in refractories, abrasives, and ceramics.
Applications of White Fused Alumina (WFA)
1. Metal Surface Treatment: Ideal for sandblasting, white fused alumina grit is used to remove oxidation and rust layers efficiently and is reusable without leaving residue.
2. Abrasive Product Manufacturing: A critical component in cutting wheels, grinding wheels, polishing wheels, sharpening stones, and honing stones, our white fused aluminum oxide enhances durability and precision.
3. Ceramics: Used extensively in ceramic membrane production, including flat and tubular alumina ceramic membranes and other ceramic components.
4. Glass and Non-Metal Surface Treatment: Perfect for sandblasting, polishing, and etching of glass and non-metallic materials, providing precise surface preparation.
5. Semiconductor Industry: Ideal for surface treatment in semiconductor components, vacuum sputtering preparation, and impurity removal from wafer backsides.
