SILICON

Basic properties

Silicon material is a semi-conductor.
Its electrical conductivity is a lot inferior than metal ones.
It is not soluble in water (except at high temperature).
Silicon is attacked by hydrofluoric acid (HF) or mixed hydrofluoric and nitric (HNO3) depending on its phase.
The electrical conductivity of semi-conductor is between the insulators ones, and metal ones.

Applications

Semi-conductors
Photovoltaïc
Mechanical components
Aerospatial
