White Fused Alumina Micropowder for Hardware & Mechanical Polishing Main component: Fused α-Alumina, Al₂O₃ ≥99.2%. Mohs hardness 9.0. Low iron and low sodium content. It hardly causes blackening or staining on stainless steel/carbon steel hardware parts. Suitable for vibratory finishing, tumbling polishing, surface lapping, raw material for polishing paste & slurry, oilstone & grinding brick

White Fused Alumina Slurry for Optical Lens Polishing Positioning: White fused alumina polishing slurry is only used for fine grinding and pre-polishing after milling. It cannot achieve final mirror polishing; cerium oxide polishing slurry shall be adopted for the final mirror finishing. Core Features: α‑Al₂O₃ with Mohs hardness 9, high cutting efficiency and chemical inertness.

Can Platelet Alumina be used as abrasive filler for sapphire substrate polishing pad? Answer: Yes. Platelet alumina (plate-shaped α‑Al₂O₃) is suitable as grinding filler for fixed-abrasive polishing pads for sapphire substrates, mainly applied in rough and intermediate polishing stages. Since sapphire is single-crystal α‑alumina, platelet alumina is the same material system and avoids foreign contamination.

White Fused Alumina Application in Floor Coatings White Fused Alumina (WFA, high‑purity fused α‑Al₂O₃, Mohs hardness 9.0) serves as a high‑end wear‑resistant aggregate and functional filler for epoxy, polyurethane and polyurea floor coatings. Featuring light‑colored cleanliness, heavy‑duty abrasion resistance, anti‑slip property and chemical resistance, it is an irreplaceable premium raw material compared with quartz sand

Pickled High‑purity White Fused Alumina is produced by arc‑fusing high‑purity alumina powder, followed by pickling, magnetic separation and hydraulic classification processes. It features Al₂O₃ ≥99.2% with extremely low contents of iron, sodium and heavy‑metal impurities, which prevents black‑spot defects on alumina ceramic substrates. Strict particle‑size classification controls over‑sized particles, greatly reducing substrate scratching risks during
