Why is our alumina so pure?
🧪1. High raw material purity
We select high-grade aluminum sources (such as high-purity aluminum hydroxide or high-purity metallic aluminum) as raw materials.
⚙️2. More Refined Production Processes
Using high-purity refining processes such as the chlorination-oxidation method, the alcoholate method, or the high-purity Bayer process, the purity of alumina can reach over 99.99%.
🧰3.Strict equipment and environmental control
The production process is conducted in a clean, inert atmosphere environment. Equipment materials utilize contamination-resistant substances such as quartz or Teflon to prevent the introduction of secondary impurities.
🔬4.Improved Inspection and Quality Control
Utilizing precision instruments such as ICP-MS and XRF for detection, we strictly control impurity levels of Na, Fe, Si, Ca, and other elements to ensure batch-to-batch consistency.

Application scenarios
Sandblasting & Rust Removal
White fused alumina is ideal for industrialsandblasting and rust removal. lts high hardness andsharp angular shape enable efficient cleaning ofstainless steel, aluminum, and glass surfaces without
contamination.
Metal & Stainless SteelPolishing
Fine-grain alumina powders are used in metal andstainless steel mirror polishing. With controlledparticle size and high purity, it produces smooth,reflective surfaces for molds, kitchenware, andprecision components.
Silicon Wafer Cutting
White fused alumina is used as an abrasive in multi-wire saws for silicon wafer slicing. lts uniform hardnessand thermal stability ensure precise, smooth cuts withminimal chipping in semiconductor and solar wafer
processing.
Optical Lens & LED Screen
Polishing
Ultra-fine alumina powders are used for highprecision polishing of lenses, LED substrates, and glasspanels. They provide excellent surface flatness andoptical clarity for display and imaging applications.
Abrasive Tools Manufacturing
White fused alumina is a primary raw material formaking sandpaper, grinding wheels, and oil stones. ltoffers strong bonding strength, sharp cutting action,and long service life in both bonded and coated
abrasives.
Advanced Ceramic &Insulation Materials
High-purity white fused alumina is used in wear-resistant and insulating ceramics. lt enhanceshardness, electrical insulation, and corrosionresistance, suitable for electronic components andstructural ceramics.
