Why are white fused alumina products so crucial in industry?
Built to last.
Our high-purity white fused aluminum oxide product is available in both fine micron powders for ceramics and glass, and angular to sub-angular abrasive grains to meet the needs of various industrial applications. With Al₂O₃ ≥ 99.0% and Fe₂O₃ ≤ 0.10%, and strictly controlled particle size, it enhances sintering, surface finish, and mechanical properties, while also improving grinding efficiency. The micro powder is suitable for ceramic tiles, technical ceramics, glass glazes, and polishing slurries, while the abrasive grains optimize the machining performance of resin wheels, ceramic wheels, and coated abrasives on stainless steel, ceramics, and alloys. Each batch of product comes with traceable reports including XRF/XRD, particle size, BET, and SEM, and particle sizes can be customized. Wholesale and OEM customers can obtain consistent quality, excellent surface finish, and predictable performance.
Seeing is Believing.
--How are the advantages of white fused alumina micro powder and sand grains demonstrated?
High purity and low impurities - Al₂O₃ ≥ 99.0%, Fe₂O₃ ≤ 0.20%, reducing sintering defects and grinding contamination.
Narrow particle size/strict mesh tolerance - Compact PSD (laser particle size distribution) of the micro-powder, resulting in uniform abrasive grains (60#, 70#, 80#, 90#, 100#, 120...), improving surface uniformity and grinding wheel performance.
Controllable morphology and specific surface area - SEM displays near-spherical or subangular particles selectable according to application, offering adjustable sintering activity and dispersibility.
Self-sharpening and durability - White Corundum for Abrasives grains generate new cutting edges during cutting, extending grinding wheel life while maintaining cutting efficiency.
Low hygroscopicity and good dispersibility - Optimized surface treatment and dispersants ensure uniform suspension of the micro-powder in the slurry, stabilizing the abrasive grains in resin/ceramic grinding wheels.
To Do a Good Job, One Must First Sharpen Their Tools.
--What are the application scenarios and selection recommendations for white fused alumina?
For White Corundum Powder for Ceramics and Glass :
Ceramic ceramic bodies: 0.8–3 µm, narrow PSD, reducing unwanted cracking and porosity.
Polishing slurry: 0.5–2 µm, near-spherical material shape, improving the overall dispersibility and smoothness of aluminum oxide material products.
Glass-ceramic composite filler: 2–8 µm, addressing the balance between thermal expansion coefficient and structural strength.


Distance Tests a Horse's Strength, Time Reveals One's Heart?
--A thousand words are not as effective as a single example of trust.
A manufacturer in Europe specializing in ceramic products initially invested heavily in procurement. However, at an exhibition, they met us, a supplier of key raw materials. We suggested that they use 1200# grade white fused alumina micro powder, which indeed improved the product's condition, increasing the firing density by 0.8% and reducing surface defects by 30%.
Even if a deal falls through, goodwill remains.
