|Title:||STRUCTURAL PHASE-TRANSITIONS IN RBLISO4|
|Abstract:||Unpolarized Raman spectra of RbLiSO4 were obtained for pressures in the range 1 atm-9.5 GPa. Several modifications cations observed in the spectra were interpreted in terms of two-phase transitions. The critical pressures for these transitions were determined as 2.5 and 5.5 GPa on increasing the pressure. The first transition is irreversible and can also occur for pressures <2.5 GPa, although through a process varying slowly. The higher pressure transition is reversible but with a marked hysteresis.|
