Description

Description générale

Brockmann aluminum oxides are suitable for column chromatography and adsorptive filtration.

The product is basic activated aluminum oxide (Alumina, Al₂O₃) having an activity grade Brockman I. The mechanism of formation of protective scales of α-Al₂O₃ on surfaces of binary M-Al (M = Fe, Ni or Co) alloys at high temperatures has been studied. Activated aluminum oxides having different acidities and water concentrations (having Brockmann activity I-V) can easily detect various types of water (namely free water, pore water, and bound water) on the aluminum oxide present in soils.

Application

Aluminum oxide (Alumina) has been used for the removal of peroxides from the dehydration solvent (tetrahydrofuran, THF) in a protocol. Protocol involved the high resolution study of fine brain anatomy of fluorescently labeled mouse brains.
It may be used in the fabrication of polycrystalline lithium iodide-aluminum oxide solid electrolytes. The incorporation of aluminum oxide remarkably increased the conductivity of lithium iodide.
