(b) mixing said precursor with at least one lithium salt selected from LiOH, Li2O, Li2CO3, and LiNO3, thereby obtaining a mixture,
(c) adding at least one phosphorus compound of general formula (I)
XyH3-yPO4 (I)
wherein
X is selected from NH4 and Li,
y is 1 or 2,
to the mixture obtained in step (b),
wherein steps (b) and (c) may be performed consecutively or simultaneously,
(d) treating the mixture so obtained at a temperature in the range of from 650 to 950° C.-
