Aluminum
(*2) Aluminum isotopes' mass numbers range from Al-23 to Al-30. Only Al-27 (stable isotope) and Al-26 (radioactive isotope) occur naturally. (*3) Aluminum has many uses ranging from kitchen utensils to the siding used for decorating the outside of a house to various other industrial applications. -industrial applications where a strong, light, easily constructed material is needed -although its electrical conductivity is only about 60% that of copper per area of cross section, it is used in electrical transmission lines because of its lightness and price -alloys are of vital importance in the construction of modern aircraft and rockets -aluminium, evaporated in a vacuum, forms a highly ref
(*6) Dust from talcum powder, baby powder, cat-box litter, cement, asphalt mixes, tobacco smoke and ashes all contain aluminumsilicates. In 1854 Henri Sainte-Claire Deville, in France, obtained the metal by reducing aluminum chloride with sodium. (*6) one of the most toxic by-products of aluminum manufacture, sodium fluoride, is added to many public water supplies. All tested miners scored in the "impaired" range. (*6) From 1940-1980, gold miners in Canada inhaled aluminum metal dust (thinking it would protect them from the silica dust inherent in gold ore). In addition, questions have been raised about the potential risks to infants who drink baby formula containing aluminum. companies are the largest single producer of primary aluminum. Aided by the financial backing of Napoleon III, Deville established a large-scale experimental plant and displayed pure aluminum at the Paris Exposition of 1855. (*6) Complex ionic aluminosilicates go directly to the brain through the olfactory system. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings.
