Activated alumina boasts a remarkable characteristic: its high reactivity. During its use, we can tailor the preparation processes to meet the specific needs of various industries, such as powder preparation. Since powder is more convenient to use, we can utilize powder preparation to fulfill industry requirements. Do you know how the powder preparation process works? Below, we will provide a detailed introduction.
Active Scar Granules
Active Scab Granules, a product following Active Bauxite, and the next in the line of active alumina products. During the alumina production process, the scab material from the decomposition tank is activated at 400-600°C, then crushed and sifted to produce a hard, dust-free product, which requires alkali extraction treatment during production.
Section II: Preparation from ρ-Alumina
Utilizing the rehydration property of ρ-Al2O3, hydrated Bayerite serves as a binder and transforms into active alumina during calcination. Producing alumina products with ρ-alumina allows for a wide variety of shapes, and certain catalyst matrices can even be directly mixed with alumina to form powders, enabling the creation of specialized alumina products with unique shapes.
Section 3: Preparation from the thin layer of water-like stone
When added to acid, bauxite can hydrolyze a portion of its particles into aluminum gel. Mixed with aluminum hydride powder, it can be used to produce various shapes and performance of alumina products.
Here is an in-depth introduction to the preparation of active alumina powder. We hope that everyone can complete the powder preparation by following the methods and content provided above.
