Visual presentation communicates information clearly and effectively through graphical means. WikiSummarizer is a Web-based application that summarizes Wikipedia articles and presents them as Visual Summaries, Tree Views and Keyword Clouds with links to Wikipedia Knowledge Base.
WikiSummarizer is an interactive learning and teaching tool providing effective graphical visualization that reduces complex information and provides clear and attractive presentation of the essential points. The interactive summaries are easily shared and published in blogs, websites and documents as digital Visual Summaries, Tree Views and Keyword Clouds.
It is easy to collaborate and mine information using the WikiSummarizer summaries in blogs, websites, word editors, browsers, mind mapping applications, databases and content management systems.
This Visual Summary presents the keywords and the summaries of the Wikipedia article about "Silicon". The Visual Summary map and the Keyword Cloud were automatically created by WikiSummarizer.

Wikipedia article: Silicon
· Controversy about silicon's character dates to its discovery: silicon was first prepared and characterized in pure form in 1824, and given the name silicium (from Latin: silicis, flints), with an -ium word-ending to suggest a metal.
· It is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates.
· Over 90% of the Earth's crust is composed of silicate minerals, making silicon the second most abundant element in the earth's crust (about 28% by mass) after oxygen.
· Most silicon is used commercially without being separated, and indeed often with little processing of compounds from nature.
· Elemental silicon also has a large impact on the modern world economy.
· Although most free silicon is used in the steel refining, aluminum-casting, and fine chemical industries (often to make fumed silica), the relatively small portion of very highly purified silicon that is used in semiconductor electronics (< 10%) is perhaps even more critical.
· Because of wide use of silicon in integrated circuits, the basis of most computers, a great deal of modern technology depends on it.
· Naturally occurring silicon is composed of three stable isotopes, silicon-28, silicon-29, and silicon-30, with silicon-28 being the most abundant (92% natural abundance).
· The most common decay mode of six isotopes with mass numbers lower than the most abundant stable isotope, silicon-28, is β+, primarily forming aluminium isotopes (13 protons) as decay products.
· Silicon is usually found in the form of complex silicate minerals, and less often as silicon dioxide (silica, a major component of common sand).
· The crystals have the empirical formula of silicon dioxide, but do not consist of separate silicon dioxide molecules in the manner of solid carbon dioxide.
· Ferrosilicon, an iron-silicon alloy that contains varying ratios of elemental silicon and iron, accounts for about 80% of the world's production of elemental silicon, with China, the leading supplier of elemental silicon, providing 4.6 million tonnes (or 2/3 of the world output) of silicon, most of which is in the form of ferrosilicon.
· It makes up about 20% of the world total elemental silicon production, with less than 1 to 2% of total elemental silicon (5–10% of metallurgical grade silicon) ever purified to higher grades for use in electronics.
· Silicon dihalides are formed by the high temperature reaction of tetrahalides and silicon; with a structure analogous to a carbene they are reactive compounds.
· Silicon dioxide is a high melting solid with a number of different crystal forms; the most familiar of which is the mineral quartz.
· Pure monocrystalline silicon is used to produce silicon wafers used in the semiconductor industry, in electronics and in some high-cost and high-efficiency photovoltaic applications.
