Abstract

Abstract: The structure of solid solutions Li_1+2xTi_2-xMg_xP₃O₁₂, in which magnesium were doped, were studied by solid-state high-resolution ³¹P MAS NMR with P atom as a probe of the structure. The relationship between ³¹P NMR lines with different chemical shifts and the local structure units Q°in solid solution systems were determined by using a linear correlation between ³¹P isotropic chemical shift and field strength F of the cation of the second coordination sphere. These results give interpretation for the change of local structure due to the substitution of titanium by magnesium.

Key words: Solid solution, NMR, Phosphates
