| titleOfInvention | Metal phosphates and process for their preparation |
| abstract | Process for the preparation of a monometallic or mixed metallic phosphate of the type (M1 M2 M3 ... Mx) 3 (PO 4 ) 2 · aH 2 O where 0 ≤ a ≤ 9, where (M1, M2, M3 ... Mx) is the one Represent metal of the monometallic or the plurality of metals of the mixed metal phosphate and include Mn, Fe, Co, Ni, Sc, Ti, V, Cr, Cu, Zn, Be, Mg, Ca, Sr, Ba, Al, Zr, Hf, Re , Ru, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu are selected with the proviso that at least one of the metals in the phosphate is Mn, Fe, Co and Ni is selected, the method being characterized in that a) preparing an aqueous solution (I) which contains at least one or more of the metals Mn, Fe, Co and / or Ni as divalent cations by reacting oxidic metal (II), metal (III) and / or metal ( IV) compounds or mixtures thereof or compounds having mixed oxidation states selected from hydroxides, oxides, oxide hydroxides, hydrated oxides, carbonates and hydroxide carbonates of at least one of Mn, Fe, Co and / or Ni together with the elemental forms or alloys of at least introducing one of the metals Mn, Fe, Co and / or Ni into an aqueous medium containing phosphoric acid and reacting the oxidic metal compounds with the elemental forms or alloys of the metals (in a redox reaction) to form the divalent metal ions, b) optionally separated solids from the phosphoric acid aqueous solution (I), c) if the phosphate is a mixed-metallic phosphate and in addition to the metals introduced into the solution in step a) further metals selected from (M1, M2, M3 ... Mx), the aqueous solution (I) further comprises at least one compound of at least one of the metals (M1, M2, M3 ... Mx) in the form of an aqueous solution or as a solid in the form of a salt, the at least one compound preferably being selected from hydroxides, oxides, oxide hydroxides, hydrated oxides, carbonates, hydroxide carbonates, Carboxylates, sulphates, chlorides or nitrates of the metals is selected, d) providing a phosphoric acid solution prepared by neutralization with an aqueous alkali metal hydroxide solution or having a pH of 5 to 8 prepared from an aqueous solution of one or more alkali metal phosphates (II); e) adding the aqueous solution (I) to the initial solution (II) and at the same time adding a basic aqueous alkali metal hydroxide solution in such a way that the pH of the resulting reaction mixture is kept in the range from 5 to 8, preferably 6 to 7, the phosphate of the type (M1 M2 M3 ... Mx) 3 (PO 4 ) 2 · aH 2 O is precipitated, f) separating the precipitated phosphate from the reaction solution. |
