Fused Alumina is an essential engineered material, powering the abrasive and refractory markets worldwide. Its combination of extreme hardness, thermal resistance, and chemical stability makes it integral to applications ranging from grinding wheels and sandblasting to kiln linings and advanced ceramics. China's place at the forefront of global Fused Alumina production is secured by deep bauxite resources, technical agility, and world-class manufacturers. This article highlights the top 10 Fused Alumina producers in China, with Dragon Abrasives Group Limited in the leading position.
Fused Alumina (Al₂O₃) is a synthetic corundum material created by melting purified alumina in electric arc furnaces at temperatures exceeding 2000°C. Grinding and refractory industries employ different grades—including brown, white, black, and even pink—each with distinct physical and chemical profiles.[2][6]
- Brown Fused Alumina: Made from bauxite, infused with a small percentage of iron and titanium oxides. Used in general abrasives and refractory bricks.[8][2]
- White Fused Alumina: Originates from pure alumina (Al₂O₃). Renowned for high purity, sharp granular edges, and resistance to chemical attack.[6][7]
- Black/Pink Fused Alumina: Tailored for specific abrasive needs.
Key attributes:
- Mohs hardness of ~9.0 (second only to diamond and silicon carbide)
- Melting point above 2000°C
- High thermal and electrical insulation properties
Fused Alumina is cast or crushed into precise grain sizes or powder, ready for industrial use in circumstances demanding reliability, longevity, and custom performance.[1]
China's ascendancy in Fused Alumina supply is due to its abundant natural resources, efficient infrastructure, and real-time access to global markets. Manufacturers leverage investments in advanced fusion furnaces, automated classification facilities, and chemical refinement technologies.[9][10]
Chinese Fused Alumina's value equation stems from:
- Extensive sourcing of bauxite and alumina
- High-volume, cost-effective electric arc fusion
- Flexible product ranges supporting OEM, refractory, and abrasive industries
- ISO-level quality management and process traceability
The production of Fused Alumina is an intricate, multistage operation aimed at achieving purity, consistency, and controlled crystal structure.
Only high-grade bauxite (for brown) or pure alumina (for white) is selected. Additives (iron filings, coke, or titanium dioxide) are proportioned to control crystal size and grain toughness.[3][2]
The blend is charged into an electric arc furnace. Under a controlled reducing environment, powered by carbon electrodes, temperatures rise above 2000°C, liquefying the mix and causing complete fusion. The electric arc shortens as power is finely managed, reducing sodium content and enhancing alumina purity.[4][3][6]
Molten Fused Alumina cools and solidifies, usually in ingot or block form. The mass is ground and crushed, yielding angular grains or powder.[5][4][8]
Acid washing (typically hydrochloric and hydrofluoric acids) removes residual soda and silica. Water washing follows, eliminating iron and carbon contaminants. The crystal grains are then sieved and sorted; high-purity grades approach 99.95% Al₂O₃, with sodium oxide below 0.05% by weight.[7][3]
After sorting and grinding, grains and powders are dried at controlled temperatures and packed according to client specifications, ready for shipment.
Leading manufacturers in China continually refine furnace designs, achieve lower impurity levels, and adapt processing for tailored grain shapes, enabling competitive performance in advanced abrasive and ceramic applications.
