5 FAQs of Alumina Powder Calcined Alumina Powder 325 Mesh

What is calcined alumina powder?
Calcined alumina powder is aluminum oxide. It’s made by heating alumina hydrate to very high temperatures. This heating process removes water. It changes the crystal structure. The result is a very hard, stable material. It’s mostly pure alpha alumina crystals.

What makes calcined alumina powder special?
This powder has important properties. It is extremely hard. It resists high temperatures well. It shows good chemical stability. It doesn’t easily react with acids or alkalis. It offers excellent electrical insulation. Its hardness makes it very wear resistant. These traits make it useful in tough jobs.

Why is the 325 mesh size important?
The mesh size tells you the particle fineness. 325 mesh means particles pass through a screen with 325 openings per inch. This equals particles roughly 44 microns or smaller. This size gives a good surface area. It still flows decently. It fills molds well for ceramics. It mixes smoothly in slurries. It provides a consistent finish in polishing. Finer powders might cake; coarser powders might not smooth well.

Where is 325 mesh calcined alumina used most?
It’s common in several industries. Ceramics use it for kiln furniture and technical ceramics. Refractories use it in high-temperature linings and shapes. It’s a key abrasive in grinding wheels and blasting media. It’s used in friction materials like brake pads. It appears in some special coatings and sealants. It polishes metals and stones effectively.

Is handling calcined alumina powder safe?
Handle it carefully. The fine powder creates dust. Breathing this dust can irritate lungs. Wear a dust mask or respirator. Use good ventilation. Wear safety glasses to protect eyes. Wear gloves to prevent skin dryness. Avoid creating clouds of dust. Follow the safety sheet for specific handling rules. Store it dry in a sealed container.
