High-pressure phase transitions in MgSiO
✍ Jahn, S. 📂 Article 📅 2008 🏛 Mineralogical Society of America 🌐 English ⚖ 985 KB

Molecular dynamics simulations and first-principles electronic structure calculations are used to study the structural behavior of orthoenstatite, MgSiO 3 , at high pressures. The calculations suggest two possible high-pressure polymorphs of orthoenstatite, one with P2 1 ca and the other with Pbca s

## Abstract We studied polymorphic transitions occurring in β‐Ge~3~N~4~ metastably compressed to high pressures (__P__ = 40 GPa) at room temperature. Previous studies under high‐pressure–high‐temperature conditions have shown that this phase transforms into a newly discovered spinel‐structured mate
