The Dequadis®, Dequasol and Dequagel boehmites

DEQUACHIM manufactures and markets boehmites and pseudo-boehmites – very-high-purity hydrated aluminas (aluminium oxihydroxide) – under the names Dequadis®, Dequasol and Dequagel.

Boehmite and pseudoboehmite alumina​
Ceramic abrasive grains

Dequadis® is a very-high-purity boehmite, of which the very high dispersibility in aqueous media makes it possible to obtain a stable and easily usable hydrosol for applications involving the SOL-GEL process in particular.

Dequasol is a boehmite supplied in the form of a ready-to-use stable colloidal suspension.

Dequagel is a very-high-purity pseudo-boehmite, non-peptisable, partially dispersible and available in different grades that can be used in particular as a catalyst support.

Our team of highly qualified engineers and our range of production and analysis equipment allow us to offer an array of products whose main physical parameters can be adjusted according to needs and target applications.

Numerous advantages

  • Very high purity
  • Highly dispersible
  • Very wide range of physical properties (specific surface area, crystallite size, etc.).

Packaging

Boehmites can be packed in drums or big bags.
