Silicon is pronounced: guī.

Stroke order: horizontal, apostrophe, vertical, horizontal fold, horizontal, horizontal, vertical, horizontal, horizontal.

I. Basic Interpretation

Nonmetallic element, symbol Si (silicium). Black and gray crystals or powder, very widely distributed in nature, ordinary sand is impure silicon dioxide. Silicon has a unidirectional conductivity, is an important semiconductor material, can also be used to make alloys. The old name silicon.

Two, detailed interpretation

Noun: a four-valent non-metallic elements, in the form of compounds, as the second most abundant element in the earth's crust after oxygen, usually in an electric furnace by the carbon reduction of silicon dioxide and the production of the main alloy used in the form of alloys (eg, ferrosilicon alloys), but also with ceramic materials used for ceramics in the metal or used as a semiconductor material (such as in the transistors) and as a component of photovoltaic cells - element symbol Si.

Three, grouping words

Silicon Valley, diatom, silicone, silicone steel, silica, organosilicon, silicate, monocrystalline silicon, silicone rubber, controllable silicon, silicon dioxide, liquid-crystal-coated silicon.

Four, application areas

1, high-purity monocrystalline silicon is an important semiconductor material. In the single crystal silicon doped with trace elements of the IIIA group, the formation of p-type silicon semiconductor; doped with trace elements of the VA group, the formation of n-type semiconductor.

2, metal ceramics, an important material for cosmic navigation.

3, optical fiber communication, the latest modern means of communication.
