Syntheses and DTA Studies of the Phase Behavior of LiAlyCo0.96-yMg0.04O2(y=0.3,0.7)

Abstract

Abstract: Aseries of LiAl_yCo_0.96-yMg_0.04O₂(y=0.3,0.7) powders were synthesized by using citric acid method, and the effect of the sintering temperature on the phase behavior of the materials with different Al contents was studied by DTAand XRDmeasurement.Asingle phase solid solution with α-NaFeO₂structure forms at 600℃ when the content of ALIs low(y=0.3), while γ-LiAlO₂emerges at 600 and 700℃ when the content of ALISIncreased to y=0.7. Asingle phase solid solution can be obtained if the sintering temperature reaches at 800℃.

Key words: LiAl_yCo_0.96-yMg_0.04O₂, Synthesis, DTA, XRD
