5 FAQs of Pure Alumina Powder Calcined Alumina Powder

Pure Alumina Powder Calcined Alumina Powder FAQs

What is calcined alumina powder?
Calcined alumina powder is aluminum oxide (Al2O3) made very pure. We heat up aluminum hydroxide to very high temperatures. This process removes water and changes its structure. The result is a hard, stable powder. It’s mostly alpha-alumina crystals.

Why is high purity important?
High purity means almost no impurities. Impurities can weaken final products or change their color. For demanding uses like electronics or advanced ceramics, purity is critical. It ensures consistent performance and reliability. Our powder is over 99.5% pure.

How heat resistant is this powder?
Calcined alumina powder handles extreme heat very well. It doesn’t melt until over 2000°C. This makes it perfect for things needing to withstand high temperatures. Refractory linings and kiln furniture are common examples. Its structure stays stable under heat.

What particle sizes do you offer?
We supply many different particle sizes. You can get very fine powders or coarser grades. Particle size affects how the powder flows and packs. It also changes the final product’s density and surface finish. Choosing the right size matters for your specific process.

Is the powder safe to handle?
The powder itself is chemically inert. It doesn’t react easily. Handle it carefully though. Avoid breathing in the dust. Wear a dust mask. Use good ventilation. Keep it away from your eyes and skin. Follow standard safety practices for fine powders.
