Silicon vs Silicone

[MolaKule]

For the question of the day, describe or the define the difference between silicon and silicone.

This question is posted since we have had some misunderstandings of these terms in the Oil Analysis sections.

I'll take a shot.

Silicon is the most abundant part if the earths crust. It is formed by sand exposed to extreme heat 2200C. Because so much of it is on the earths surface it often erodes and forms dust which makes up the "dirt" we see in the UOA's.

Silicone is derived from silicon and is used to make anti drain back valves and fake breasts.

BA-BOOM!!

Silicon is a hard crystalline substance (as in rock) and as in the computer chips in Silicon Valley.
Silicone is associated with silicone spray lubricants and high temperature silicone rubber and the like...... and breast implants.

This is a layman's definition, but I think I've lead you in teh right way.

Its siliconE with an E (Sil-i-cone) that you'll hear in association with your vehicles.

Good work.

Silicon is a basic element of the periodic table and silicone(s) are usually in the form of polymers, such as adhesives and formable gasket makers, such as RTV.

Since silicones contain silicon, they often "leach" their silicons into the oil as in a new vehicle or after a gasket replacement, which may bias the oil analysis results.

Wait a minute MolaKule...
I didn't realize you were a freakin' Rocket scientist (I just checked your profile.)
I thought you were asking this question because you were not sure of the difference.

In fact I'm not really sure myself. So is silicone made from silicon? I've long wondered. Do tell us more about their relationship.
