5 FAQs of High Purity Calcined Alumina Powder /calcined Sintered Alpha Alumina Low Sodium Type Refractory 99% min

What is High Purity Calcined Alumina Powder?
This is a special white powder made from aluminum oxide. We heat it very hot (calcined) to make it strong and stable. It’s the alpha sintered type, meaning its crystals are packed tight. It has very little sodium, under 0.1%. The main ingredient is at least 99% pure.

Why is low sodium important?
Sodium is bad in high-heat situations. Too much sodium makes the alumina weaker when it gets hot. It can also cause problems later if the alumina is used in ceramics or electronics. Low sodium keeps the material strong and reliable at extreme temperatures.

Where is this alumina powder mainly used?
Its main job is in things that handle extreme heat, called refractories. Think furnace linings or kiln parts. It’s also vital for making advanced ceramics, like cutting tools or wear-resistant parts. Some electronics use it too, for insulating parts or substrates.

How does high purity help performance?
Purity matters a lot. More than 99% pure alumina means fewer unwanted elements. These impurities weaken the final product. High purity makes ceramics denser and stronger. It also helps the material resist heat shock better. This means less cracking and longer life.

How should I store this powder?
Keep it dry. Moisture is the enemy. Store the bags or drums in a covered warehouse. Make sure the place is well-ventilated. Keep the powder away from anything that could contaminate it, like dirt or other chemicals. Keep the bags sealed until you need the powder.
