The followinguses for silicon are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additionalreferenced uses.

• doped with boron, gallium, phosphorus, or arsenic, etc. to produce silicon for use in transistors, solar cells, rectifiers, and other electronic solid-state devices
• silicones are important products of silicon. They are prepared by hydrolysing a silicon organic chloride, such as Me₂SiCl₂
• silica, as sand, is a principal ingredient of glass, a material with excellent mechanical, optical, thermal, and electrical properties
• computer chips
• lubricants
• used to make concrete and bricks
• used in medicine for silicone implants
