HiQ® boehmite alumina

BASF HiQ® high purity boehmite alumina are available as white, free-flowing, spray-dried powders. The manufacturing process for BASF HiQ boehmite alumina begins with primary aluminum to produce an alumina of extraordinary purity. This is unlike other processes that start with trihydrate and yield aluminas which are subject to common impurities such as sodium, iron or silica. High purity denotes very low levels (less than 0.01 wt percentage> of such impurities.

HiQ boehmite alumina consist of small boehmite crystals, often referred to as pseudoboehmite. The crystalline character of each alumina is controlled in order to tailor their chemical and physical properties.

HiQ 10 alumina exhibits the smallest crystallite size and is mainly used for making extruded catalysts.

HiQ 20 alumina is the general purpose grade of alumina and is easy to mull and extrude.

HiQ 30 alumina is typically used as the binder for extruded oxide blends. Additionally, supports made from these products have very narrow micro / meso pore distributions.

HiQ 40 alumina offers the largest crystallite size and is well suited for applications requiring exceptionally high acide dispersibility or binding ability.

HiQ boehmite alumina is a specialty product and its applications are quite diverse. They include chemical catalysts, automotive washcoat catalysts, catalyst binders and supports, sol-gel abrasives, polishing compounds, viscosifiers and anti-skid agents.
