XR alumina Pseudoboehmites powders are high quality alumina powders produced to meet stringent standards in variety of applications in chemical, ceramics and other related industries. Pseudoboehmites are used in manufacturing of catalysts supports, binders, abrasives, polishes, automotive wash coats and ceramic coatings.
XR alumina pseudoboehmite powders exhibit spherical particle shape with d50 2-40um.
Alumina Pseudoboehmite Powders in XR include NH-P-D,XR-DF-03-LS，NH-P-DF series,DH-QP-DFH series, DC-P-DF series are for your choose.
As alumina Pseudoboehmite phase-transitions upon thermal exposure, surface area and porosity characteristics are also changing. If not subject to any thermal exposure (but only mild dehydration), surface areas for NH-P-DF series and DH-QP-DFH series are in vicinity of 400 m2/g and 300 m2/g, correspondingly. Conversion to gamma phase at 500–550 °C are accompanied by extensive dihydroxylation and decrease in surface area to ~300 and 250 m2/g. Further temperature increase results in almost linear decline of surface areas and diminishing surface area difference for both products. Transition to alpha-phase at 1100 °C and above yields alumina with surface area below 50 m2/g (depending on temperature used).
Designed to meet your alumina needs.
Alumina Pseudoboehmite properties are customizable offering unique opportunity to tailor key parameters such as surface area, porosity, bulk density, acidity and particle size.
