Beschreibung
- Alumina A is widely used to remove water from gas streams.
- Also used for its hardness and strength.
- It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond.
- Many types of sandpaper use aluminium oxide crystals.
- In chemistry laboratories, alumina is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations, as well as for alcohols, hydrocarbons, steroids, alkaloids and natural pigments.
- Neutral alumina, (less active than the basic form) is useful for separation of aldehydes, ketones, quinones, esters, lactones, and glucosides.
- Acidic alumina, is the weakest and least often used type.
- Alumina is useful for separation of acid pigments and strong acids.
- It can cause polymerization, condensation and dehydration reactions.
- Neither acetone nor ethyl acetate should be used as eluants, the latter being subject to saponification.
- It is used as a dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties.
