Main Page | See live article | Alphabetical index Inorganic compound is a chemical term initially meaning a substance derived from living organisms, or found in living organisms. It was later broadened in use to include most compounds containing carbon, other than very simple substances such as carbon dioxide (CO2) or simple carbonates. Elemental carbon (diamond or graphite) is typically considered inorganic. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
