5 FAQs of Chinese High Purity Calcined/Reactive Alumina Powder Ceramic Powder Aluminium Oxide For Refractory Raw Material

What is high purity calcined/reactive alumina powder?
High purity calcined alumina powder is aluminum oxide treated at high temperatures. This process increases density and hardness. Reactive alumina powder has a lower calcination temperature. It stays more chemically active. Both types are used in ceramics and refractories.

How do calcined and reactive alumina differ?
Calcined alumina undergoes heating above 1200°C. This removes impurities and stabilizes the structure. It becomes harder and less reactive. Reactive alumina is heated at lower temperatures. It retains higher surface area and reactivity. Calcined alumina suits high-strength applications. Reactive alumina works better for bonding or chemical processes.

What industries use this alumina powder?
The main users are refractory and ceramic industries. Refractory materials need high heat resistance. Alumina powder strengthens bricks and linings for furnaces. Ceramic manufacturers use it to improve durability and thermal stability. Electronics and coatings industries also use it for specialized products.

Why is purity important in alumina powder?
Higher purity means fewer impurities like silica or iron. Impurities weaken heat resistance and chemical stability. Purity levels above 99% ensure better performance in extreme conditions. High-purity alumina lasts longer in refractory applications. It prevents contamination in advanced ceramics.

How should this alumina powder be stored?
Keep it dry and sealed in moisture-proof packaging. Humidity causes clumping and reduces reactivity. Store containers in cool, ventilated areas away from direct sunlight. Avoid contact with acids or strong alkalis. Use protective gear when handling to prevent inhalation or skin contact.
