5 FAQs of Low Refractory Grade Calcined Alumina Powder A-al2o3 High Purity Calcined Alpha Alumina Powder s

What is Low Refractory Grade Calcined Alumina?
This powder is a type of aluminum oxide (Al2O3). It’s made by heating alumina to very high temperatures. This process changes it into alpha alumina. Alpha alumina is the stable, hard form. This grade is less resistant to extreme heat than other calcined aluminas. It’s chosen for jobs needing high purity alumina but not the highest heat resistance.

Where is this alumina powder used?
People use it in many industries. It’s common in abrasives for grinding and polishing. Ceramic producers add it to glazes and bodies. It helps make technical ceramics harder. It’s also used in friction materials like brake pads. Some paints and coatings use it for durability. It works well where high purity matters more than extreme heat performance.

Why choose this over regular calcined alumina?
This powder offers a good balance. It has high purity like premium grades. It costs less than high refractory grades. It performs well in many applications. It doesn’t need the highest heat resistance. You get reliable quality for a lower price. This makes sense for cost-sensitive projects needing pure alumina.

How pure is this alumina powder?
The purity is very high. It typically contains over 99% Al2O3. Impurities like silica and iron oxide are kept very low. This high purity is important. It ensures consistent performance. It prevents unwanted reactions in final products. You get clean, reliable material for demanding uses.

What is the particle size like?
The particle size can vary. Manufacturers often offer different sizes. Common sizes are fine powders like 325 mesh. Finer sizes are available too. The specific size depends on your needs. Smaller particles give smoother finishes. Larger particles might be better for certain abrasives. Particle size directly affects how the powder performs in your application.
