5 FAQs of High Purity Alumina Powder Aluminium Oxide Polishing Powder

What is High Purity Alumina Powder? High Purity Alumina Powder is a white powder made from aluminium oxide. It has very high purity levels, often above 99.99%. This powder is ideal for precision polishing tasks. It works well on surfaces needing a smooth finish.

What are the main uses of this powder? It polishes materials like metals, glass, and semiconductors. It is also used in LED manufacturing. Another key use is in lithium-ion battery coatings. This powder ensures high-quality results in these applications.

How does it differ from regular alumina? Regular alumina has lower purity, usually below 99%. Impurities affect its performance. High purity versions remove flaws better. They leave no residue on polished surfaces. This makes them essential for sensitive electronics.

What particle sizes are available? Sizes range from coarse to ultra-fine. Common options include 1 micron, 0.3 micron, and 0.05 micron. Coarser grits tackle deep scratches quickly. Finer grits achieve mirror-like finishes. Users pick sizes based on their project needs.

How should I store this powder? Keep it in a cool, dry place. Seal the container tightly after use. Moisture causes clumping and reduces effectiveness. Avoid direct sunlight or heat sources. Proper storage maintains its polishing power for years.
