Gallium: the backbone of the electronics industry :- Gallium is a silvery blue and soft metallic element that enjoys vast application in optoelectronics (e.g., LED's), telecommunication, aerospace, and many commercial and household items such as alloys, computers and DVD's. Albeit that gallium represents a small annual tonnage of material, its important impact as the backbone of the worldwide electronics sector goes unnoticed by the popularity of key base metals such as Cu/Ni/Co and attraction of the platinum group metals. Although gallite is a host mineral, gallium occurrence is associated with aluminosilicates such as bauxite and clays, plus zinc-bearing ores (e.g., sphalerite). Gallium is extracted primarily from the residue obtained during the processing of aluminum and secondly via electrolytic zinc. Other sources include fly ash collected from burning coal. Whilst countries such as Australia, China, Germany, Kazakhstan, Japan and Russia are the main suppliers of primary (i.e., ...moreAnswered by Rabindranath Sahu, 19 Feb '09 10:45 pm
