Chemie und Industrie
Pharmakologische Informationen
Metabolism/Metabolites
Aluminum is poorly absorbed following either oral or inhalation exposure and is essentially not absorbed dermally. The bioavailability of aluminum is strongly influenced by the aluminum compound and the presence of dietary constituents which can complex with aluminum and enhance or inhibit its absorption. Aluminum binds to various ligands in the blood and distributes to every organ, with highest concentrations found in bone and lung tissues. In living organisms, aluminum is believed to exist in four different forms: as free ions, as low-molecular-weight complexes, as physically bound macromolecular complexes, and as covalently bound macromolecular complexes. Absorbed aluminum is excreted principally in the urine and, to a lesser extent, in the bile, while unabsorbed aluminum is excreted in the faeces. (L739)
Verwendung und Herstellung
Uses
Used to reduce metal oxides and to make aluminum nitride and methane; [Merck Index] Also used as a catalyst, drying agent, and in metallurgy; [Hawley]
Metal Extraction and Refining [Category: Industry]
Aluminium carbide is a common impurity of technical calcium carbide and often forms as a corrosion product of graphite electrodes. It is used an abrasive in high-speed cutting tools and in pyrotechnics. (L750)
