Aluminium (or aluminum in North American English) is a chemical element in the periodic table that has the symbol Al and atomic number 13. A silvery and ductile member of the poor metal group of elements, aluminium is found primarily as the ore bauxite and is remarkable for its resistance ...
As an aluminum alloy board null essential elementPROBLEM TO BE SOLVED: To prevent wrinkling and cracking at necking for a mouth part and subsequent threading and curl forming while satisfactorily securing the strength after baking (pressure resistance of cans) of bottle type cans.松崎和彦...
In the absence of Al, the synthesized oxalate could not make complex with Al but makes insoluble precipitation with alkaline earth metals, such as Ca and Mg in plant, possibly resulting in deficiency of these nutrient cations. 展开 关键词: Element Toxicity and Remediation aluminum accumulator ...

Aluminum as the third most abundant element in the earth cannot be found as a free element in nature (Abdulkadir et al., 2015). Aluminum is the second most widely used metal after iron. It is a lightweight, conductive, easily paintable, malleable, corrosion resistant, non-magnetic, water/...

Aluminum is the third most abundant element in the crust of the earth, accounting for 8.13% by weight. It does not occur in free elemental form in nature, but is found in combined forms such as oxides or silicates. It occurs in many minerals including bauxite, cryolite, feldspar and granit...
The most important aluminum ore, an iron-containing rock consisting of about 52 percentaluminum oxide, was discovered in 1821 nearLes Bauxin southern France. The material was later namedbauxite. Bauxite is best defined as an aluminum ore of varying degrees of purity in which aluminum in the for...
