Abstract:
A process for preparing transition metal mixed oxide precursors, including: (A) precipitating, from aqueous solution at a pH of 8.0 to 9.0, a compound of formula (I): M(CO3)bOc(OH)dAmBe(SO4)fXg(PO4)h (I), wherein: M is one or more transition metals, A is sodium or potassium, B is one or more metals of groups 1 to 3, excluding Na and potassium, X is halide, nitrate or carboxylate, b is 0.75 to 0.98, c is zero to 0.50, d is zero to 0.50, where the sum (c+d) is 0.02 to 0.50, e is zero to 0.1, f is zero to 0.05, g is zero to 0.05, h is zero to 0.10, m is 0.002 to 0.1, and (B) separating the precipitated material from the mother liquor, where the particles of material of formula (I) have a spherical shape.
