5 FAQs of Al2O3 Alumina Oxide Powder/Alumina Polishing Powder/high Purity Calcined Alumina

What exactly is alumina powder?
It’s a very fine white powder made mainly of aluminum oxide (Al2O3). We make it by heat-treating aluminum hydroxide. This process is called calcination. The powder is very hard. It is also chemically stable. It doesn’t react easily with other things.

What jobs is this powder used for?
People use it widely for polishing. It works great on metals, glass, and ceramics. It gives a smooth, shiny finish. It’s also used in making special ceramics. These ceramics need high heat resistance. Another use is as a filler. It strengthens plastics and coatings.

Why is high purity important?
Purity affects performance directly. Higher purity powder cuts better. It polishes more evenly. It leaves fewer scratches. Impurities can ruin the finish. They might cause streaks or spots. For technical uses, purity ensures consistent results. It makes the powder more reliable.

How do I use it for polishing?
Mix the powder with water or oil. This makes a paste or slurry. Apply this mixture to your polishing wheel or pad. Use the right amount of pressure. Keep the surface wet. Change the slurry often. Start with coarser grit for rough work. Use finer grit for the final shine.

How should I store this powder?
Keep it dry. Moisture makes it clump. Store it in a cool place. Keep it away from direct sun. Seal the bag tightly after use. Use a container with a good lid. This stops moisture getting in. It also keeps dust out. Proper storage keeps the powder working well for longer.
