Metal Silicon

Since silicon has so many different forms that it appears in, it is very useful.

Description

Products Description

The Swedish chemist Jons Jacob Berzerlius is credited with first isolating silicon in 1823. Berzerlius accomplished this by heating metallic potassium (which had only been isolated a decade earlier) in a crucible along with potassium fluorosilicate. The result was amorphous silicon.

Making crystalline silicon, however, required more time. An electrolytic sample of crystalline silicon would not be made for another three decades. The first commercialized use of silicon was in the form of ferrosilicon.

Following Henry Bessemer's modernization of the steelmaking industry in the mid 19th century, there was great interest in steel metallurgy and research in steelmaking techniques. By the time of the first industrial production of ferrosilicon in the 1880s, the importance of silicon in improving ductility in pig iron and deoxidizing steel was fairly well understood.

Early production of ferrosilicon was done in blast furnaces by reducing silicon-containing ores with charcoal, which resulted in silvery pig iron, a ferrosilicon with up to 20 percent silicon content.

The first silicon integrated circuits were made in the 1960s and, by the 1970s, silicon-containing processors were had been developed. Given that silicon-based semiconductor technology forms the backbone of modern electronics and computing, it should be no surprise that we refer to the hub of activity for this industry as 'Silicon Valley.'
