Enstatite - Wikipedia
Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO 3) – ferrosilite (FeSiO 3). The magnesium rich members of the solid solution series are common rock-forming minerals found in igneous and metamorphic rocks.

Ferrosilite (FeSiO 3 ): Synthesis at High Pressures and Temperatures …
The FeSiO 3 (ferrosilite) end member of the pyroxene series is not known as a pure mineral in nature and cannot be synthesized at atmospheric pressure. It is readily synthesized, however, at pressures from 18 to 45 kb and temperatures from 1150° to 1400°C.
