White Fused Alumina （WFA）– Key Applications
White Fused Alumina is a high-purity, sharp, and friable synthetic mineral. Due to its exceptional hardness and chemical stability, it is widely utilized across the following industries:
- Refractories and High-Temperature Engineering
Refractory Components: Essential for the production of furnace linings, high-grade refractory bricks, castables, and ramming mass.
Precision Casting: Extensively used as a coating material for investment casting molds and as a high-performance cost-effective alternative to Zirconium powder.
Ceramic Filtration: Used in the manufacturing of high-precision ceramic filter plates and advanced separation membranes (Flat, Tubular, and Ceramic Membranes).
- Abrasives and Surface Finishing
Bonded Abrasives: Manufacturing of grinding wheels, whetstones, oilstones, and cutting discs.
Coated Abrasives: Primary raw material for high-quality sandpaper, sanding belts, and abrasive gauze.
Super-abrasive Tools: Used in the production of diamond grinding wheels and dry/wet diamond polishing pads.
Polishing Media: Used in sponge/fiber polishing wheels, polishing waxes, and liquid compounds for finishing buttons and mobile phone components.
- Surface Treatment and Sandblasting
Industrial Blasting: High-efficiency rust removal, surface cleaning, and de-burring of metal components.
Precision Treatment: Surface preparation for glass, stone, and delicate electronic parts (e.g., silver polishing sticks).
- Functional Coatings and Wear Resistance
Industrial Flooring: An ideal additive for wear-resistant epoxy floors, anti-slip coatings, and heavy-duty adhesive layers.
Protective Linings: Reinforcing fiberglass wear-resistant linings and ceramic glazes to enhance durability.
- Cosmetics and Personal Care
Dermatological Grade: Used as a high-purity exfoliating agent in skin-grinding creams and medical microdermabrasion treatments.
Cosmetic Additives: Integrated into beauty crafts and professional-grade skincare formulations for its gentle yet effective abrasive properties.
