Key Characteristics

• High Purity and Crystal Phase: Pseudoboehmite exhibits excellent crystal phase purity, ensuring consistent chemical and physical performance.
• Thixotropic Gel Behavior: This material demonstrates thixotropic properties, meaning it becomes less viscous under shear stress and returns to its original gel state when at rest.
• Versatile Physical Forms: Available as white gel (wet form) or fine powder (dry form).
• Odorless and Non-toxic: Pseudoboehmite is odorless, tasteless, and safe to handle.

Applications

Pseudoboehmite serves a variety of industrial purposes:

• Catalyst Carrier for Active Alumina: It is widely used as a precursor in the production of high-surface-area alumina catalysts, essential in refining and petrochemical processes.
• Binder for Molecular Sieves and Refractory Fibers: It acts as a forming binder for semi-synthetic rare-earth Y-type molecular sieves and silicate refractory fiber products, providing superior mechanical strength and moldability.
• Catalyst Support in Petrochemical Reactions: Commonly used in catalysts for ethanol dehydration to produce ethylene and ethylene oxide production, enhancing catalyst stability, activity, and durability.

Packaging Options

• 25 kg per bag

Storage and Transportation

• Stored in a cool, dry place away from moisture and direct sunlight.
• Kept in tightly sealed containers to prevent caking or degradation due to its hygroscopic nature.
• Transported with care to avoid exposure to damp conditions, ensuring product stability throughout handling and delivery.
