DETAIL
1. Product Overview
Ultra Fine Alumina Powder (Ultra-fine Aluminum Oxide, Al₂O₃) is a high-performance inorganic functional powder produced by high-temperature calcination, ultra-fine grinding and strict classification technology. With ultra-fine particle size, narrow particle distribution, high purity, excellent dispersion, stable chemical properties and superior thermal conductivity, electrical insulation and wear resistance, it is a core raw material widely used in advanced ceramics, electronic manufacturing, thermal conductive materials, precision polishing, new energy and refractory industries.
Our premium ultra fine alumina powder series features strict impurity control, consistent particle size distribution, and customizable particle sizes & crystal forms, fully meeting precision manufacturing requirements for global industrial and commercial B2B buyers.
2. Core Product Advantages
- High Purity & Low Impurity: The alumina purity reaches 99.9%–99.998%, with ultra-low content of sodium, iron, silicon and other harmful impurities (key impurities <1ppm for electronic grade), avoiding performance attenuation of downstream products and adapting to semiconductor and high-precision electronic scenarios.
- Uniform & Controllable Particle Size: Narrow particle size distribution, D50 ranges from 0.3μm–1μm optional, no coarse particles. Effectively improves product compactness, flatness and wear resistance of finished products.
- Stable Physical & Chemical Properties: With a high melting point, super hardness, outstanding high-temperature resistance, corrosion resistance and electrical insulation properties, our ultra fine alumina has low water absorption and stable dimensional stability, ideal for long-term high-temperature and harsh industrial working environments.
- Customization & Mass Supply: We provide professional customization for particle size, purity, surface modification and packaging of ultra fine alumina powder. With stable monthly production capacity, we support fast delivery and comprehensive after-sales service for bulk B2B wholesale and OEM orders.
3. Complete Product Specifications
We supply diversified ultra fine alumina powder series for various industrial applications, and every batch of our Al2O3 powder is accompanied by complete official quality test reports.
4. Wide Application Fields
- Electronic & Semiconductor Industry: Used for electronic ceramic substrates, semiconductor fixtures, packaging materials, battery separator coatings and insulating components. Features low radioactivity, high dimensional stability and ultra-low impurity to meet electronic grade standards.
- Thermal Conductive Materials: Ideal filler for thermal conductive silicone sheets, thermal grease, epoxy potting glue, thermal adhesive tapes and thermal plastics. High thermal conductivity and high filling rate effectively improve heat dissipation efficiency of electronic equipment.
- Precision Polishing Industry: Suitable for sapphire, optical glass, precision hardware and ceramic surface polishing. Ultra-fine particle size ensures smooth polishing surface without scratches, widely used in high-precision optical processing.
- Advanced Precision Ceramics: Applied to wear-resistant ceramic parts, structural ceramics, insulating ceramics and ceramic valves. Low-temperature sintering performance is good, which can form dense and high-strength ceramic products.
- New Energy & Chemical Industry: Serves as catalyst carrier, new energy battery functional material and biomedical scaffold material, with stable chemical properties and high safety.
- Refractory & Coating Industry: Used for high-grade refractory materials, high-temperature wear-resistant coatings and anti-corrosion coatings, improving high-temperature resistance and structural strength of products.
