AbstractThe phase transitions of two ternary fluorides have been reinvestigated by thermal and X-ray diffraction analyses. Four phase transitions have been detected at T1= 483 ± 5 K, T2= 548 ± 5 K, T3= 765 ± 5 K and T4= 867 ± 5 K for Li3AlF6. Only two transformations occurred at T1= 550 ± 5 K and T2= 660 ± 10 K for Li3CrF6. Dielectric and optical measurements performed respectively on ceramics and single crystals revealed a ferroelectric behaviour coupling partially with ferroelastic coupling for the two investigated fluorides. |
