New transitory form of silica observed

20 marzo 2015

Silicon dioxide, commonly called silica, is one of the most-abundant natural compounds and a major component of the Earth’s crust and mantle. It is well-known even to non-scientists in its quartz crystalline form. Silica’s various high-pressure forms make it an often-used study subject for scientists interested in the transition between different chemical phases under extreme conditions. A research team was able to discover five new forms of silica under extreme pressures at room temperature.
