Effect of hydrostatic pressure up to 6 GPa on the crystal structures of ammonium and sodium hexafluorosilicates, (NH4)2SiF6 and Na2SiF6; a phase transition in (NH4)2SiF6
An in situ X-ray powder diffraction study has shown the cubic modification of (NH4)2SiF6 (cryptohalite, space group Fm¯3m) at 0.2–0.3 GPa to transform irreversibly into the trigonal bararite, space group P¯3m1...
