Über die Struktur und das Hochdruckverhalten des β-Li 6 UO 6 The Crystal Structure and the High Pressure Stability of β-Li 6 UO 6
Li 6 UO 6 has a reversible phase transformation at 680°C and decomposes above about 850°C. At high pressure the low temperature modification becomes unstable because of an invariant point in the system Li 2 O—Li 4 UO 5 at approximately 13 Kb and 620°C. β-Li 6 UO 6 has a triclinic unit cell with a =...
