Low sodium Pseudoboehmite powder / soda pseudo boehmite

Low sodium Pseudoboehmite powder / soda pseudo boehmite

Na2O content of soda pseudoboehmite(pseudo boehmite) or Low Sodium Pseudoboehmite(pseudo boehmite) is below 0.1%. It adopts flash dry. It is highly welcomed in the world.

Pseudoboehmite alumina are supplied as loosely agglomerated, easily dispersed, spray-dried powders (about 50 microns mean diameter) possessing high-purity, high surface area and low bulk density. Each Versal alumina particle is built from nominal 30 angstrom (3.0 nm) crystallites through a unique acid-base precipitation process using a proprietary reactor configuration that allows control of density, particle morphology, colloidal dispersibility and thermal conversion processes.

Pseudo boehmite is material of catalyst, binder, desiccant and their carrier.  It used in nitrogen fertilizer, environmental protection, medicine, petrochemical industry, refractory and other industries , which is the most widely used material of catalyst and catalyst carrier.

Classfication of Pseudoboehmite:

  • Normal Psudoboehmite
  • Low sodium(soda) Pseudoboehmite
  • Large pore(Macroporosity) Pseudoboehmite
