Fused White Alumina Description
Fused White Alumina is a high-purity fused aluminum oxide known for its pristine white color, which results from its lower impurity levels compared to brown or pink fused aluminum oxide. Notably, it exhibits higher friability than brown fused aluminum oxide. With a Mohs hardness rating of 9, Aluminum Oxide is a robust and wear-resistant material that can withstand rigorous chemical attacks, even at extreme temperatures, such as those involving acids and alkalis. Its exceptional refractoriness, coupled with superior electrical insulating properties, dielectric properties, and high melting point, makes White Fused Aluminum Oxide an ideal material for a diverse range of applications.

Fused White Alumina Applications
1. Abrasive and Refractory Materials: Used as a high-performance abrasive in grinding wheels, sandpaper, blasting media, and polishing compounds. Its hardness and toughness make it effective for precision grinding and surface preparation in metal fabrication, ceramics, and glass industries.
2. Refractory Products: Incorporated into refractory bricks, castables, and shapes for high-temperature applications such as furnace linings, kiln furniture, and crucibles. Fused white alumina enhances thermal stability and resistance to thermal shock in harsh industrial environments.
3. Ceramic and Glass Production: Used as a raw material in the production of ceramic bodies, glazes, and glass compositions. It improves the strength, durability, and aesthetic properties of ceramic and glass products.
4. Precision Casting and Investment Casting: Applied in precision casting processes to produce intricate metal parts with smooth surface finishes. Fused white alumina is used as a mold material or ceramic shell in investment casting to achieve high dimensional accuracy and surface quality.
5. Electrical Insulation: Utilized as a filler material in electrical insulators and high-temperature insulating coatings due to its excellent dielectric properties and thermal stability. It ensures reliable insulation in electrical components and systems.
6. Metal Polishing and Lapping: Used in metal polishing applications to achieve mirror-like finishes on stainless steel, aluminum, and other metals. Fused white alumina abrasives are also employed in lapping processes for precision flat surfaces.
7. Water Filtration: Used in water filtration systems as filter media to remove impurities, turbidity, and contaminants from drinking water and industrial wastewater. Its high purity and low abrasion rate make it suitable for filtration applications.
8. Aerospace and Automotive: Employed in manufacturing components for aerospace and automotive industries, such as brake linings, clutch plates, and engine components. Fused white alumina's high strength and thermal conductivity contribute to enhanced performance and durability.
9. Cosmetics and Personal Care: Included in cosmetic products, toothpaste, and skincare formulations as a mild abrasive agent for exfoliating dead skin cells and improving skin texture.
10. Medical and Dental Applications: Used in dental abrasives for cleaning and polishing teeth and in orthopedic implants due to its biocompatibility and wear resistance.
