High pressure phase transitions of paracelsian BaAl(2)Si(2)O(8)

Three new polymorphs of aluminosilicate paracelsian, BaAl(2)Si(2)O(8), have been discovered using synchrotron-based in situ high-pressure single crystal X-ray diffraction. The first isosymmetric phase transition (from paracelsian-I to paracelsian-II) occurs between 3 and 6 GPa. The phase transition...
