Lechatelierite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
SiO2
Hardness:
Name:
Named after Henry Louis Le Chatelier (Paris, 8 October 1850 – Miribel-les-Échelles, France, 17 September 1936). He is known for Le Chatelier’s principle, which makes it possible to predict the effect a change of conditions (such as temperature, pressure, or concentration of reaction components) will have on a chemical reaction. His principle proved invaluable in the chemical industry for developing the most-efficient chemical processes.
A natural fused, X-ray amorphous silica.
Originates when lightning strikes sand or other very SiO2-rich sediments and rocks.
Lechatelierites/fulgurites form hollow tubes that are often irregular and branched.
Also forms on impact of meteorites as a result of sand melting.

The major component of the impact glass called Libyan Desert Glass.
