Product DescriptionProduct DescriptionWhite Fused Corundum GritHenan Yumo New Materials' white fused corundum micropowder represents the pinnacle of ultra-precision grinding technology. It is produced from high-purity alumina (Al2O3≥ 99.7%) melted in an electric arc furnace and processed using advanced airflow crushing and precision classification techniques. Particle sizes typically range from F230 (53 μm) to F2000 (3 μm) and even finer. Its exceptional purity, precise particle size control, excellent chemical stability, and exceptional surface modification capabilities make it an indispensable functional material in high-end manufacturing.Core Value PropositionProviding nanoscale material removal rates, damage-free machined surfaces, and exceptional batch-to-batch consistency for ultra-precision surface treatments is a key factor in improving the yield and performance of your end products.Typical ApplicationsSemiconductor CMP (Chemical-Mechanical Planarization)F1000 – F2000Ultra-high purity, zero metallic contamination, superior planarization ratePrecision optical glass & sapphire polishingF800 – F1500Achieves nano-level surface finish (Ra < 0.5 nm) without scratchesHigh-end coatings & paintsF600 – F1200Wear-resistant filler that increases coating hardness and lifetimeAdvanced ceramics & refractoriesF230 – F600Ultra-fine additive promoting higher sintered density and mechanical strength3D-printing material reinforcementF400 – F800Boosts strength, stiffness and heat resistance of PA, resin and other filamentsKey Characteristics & AdvantagesUltra-High Purity & Chemical InertnessAl2O3≥ 99.7%, with extremely low levels of key impurities (Na2O ≤ 0.2%, Fe2O3 ≤ 0.03%).Advantage: No contaminants are introduced during processing, making it particularly suitable for applications sensitive to ionic contamination, such as semiconductors and optical glass.Precise Particle Size DistributionMulti-stage hydraulic or centrifugal classification technology ensures a concentrated particle size distribution (Span < 0.8), with strictly controlled D50 and D97 indicators.Advantage: Avoids unintended scratches caused by coarse or oversized particles, achieving uniform surface roughness and predictable material removal rates.Controlled Particle MorphologySpecialized processing allows for the production of micropowders with high sphericity (>90%) or angular shapes to meet diverse application requirements. Advantages: Spherical micropowders facilitate lower surface roughness; angular micropowders provide higher cutting efficiency.Surface Modification OptionsModels treated with coupling agents such as silane are available.Advantages: Greatly improves micropowder dispersibility and compatibility in resins and oil-based/water-based systems, prevents agglomeration, enhances polishing slurry stability, and strengthens bond strength with binders.Why Choose Henan YUMO?Technological Leadership: We specialize in ultra-low sodium technology and precision grading techniques to ensure stable and reliable product performance.Customization: We offer customized particle size combinations, surface treatment solutions, and technical support tailored to your specific application.Quality Assurance: Each batch of product is accompanied by an authoritative Certificate of Authenticity (CoA), including key data such as laser particle size analysis and chemical composition.Global Service: We have extensive export experience, provide a full set of compliance documentation, and support global shipments.Recommended Related Products DisplayCompany ProfileHenan Yumo New Materials Co., Ltd. is a leading manufacturer of high-quality abrasive and refractory materials, specializing in white fused alumina, brown fused alumina, and silicon carbide.
