Silicon - definition of silicon by The Free Dictionary

sil·i·con (sĭl′ĭ-kən, -kŏn′) n. Syol Si A nonmetallic element occurring extensively in the earth''s crust in silica and silies, having both a brown amorphous and a gray lustrous crystalline allotrope, and used doped or in coination with other materials in glass, semiconducting devices, concrete, brick, refractories, pottery, and

Boiling chip - Wikipedia

A boiling chip, boiling stone, porous bit or anti-bumping granule is a tiny, unevenly shaped piece of substance added to liquids to make them boil more calmly. Boiling chips are frequently employed in distillation and heating. When a liquid becomes superheated, a speck of dust or a stirring rod can cause violent flash boiling.Boiling chips provide nucleation sites so the liquid boils smoothly

silicon | Element, Atom, Properties, Uses, & Facts

When silicon and carbon are coined at electric furnace temperatures (2,000–2,600 °C [3,600–4,700 °F]), they form silicon carbide (carborundum, SiC), which is an important abrasive. With hydrogen, silicon forms a series of hydrides, the silanes. When coined with hydrocarbon groups, silicon forms a series of organic silicon compounds.
