    • A process for producing a phosphate by: introducing oxidic metal(II)-, metal(III)-metal(FV) or compounds with mixed oxide stages selected from hydroxides, oxides, oxide-hydroxides, oxide-hydrates, carbonates and hydroxide carbonates, of at least one of the metals Mn, Fe, Co and Ni with the elemental forms or alloys of at least one of the metals Mn, Fe, Co and/or Ni into an aqueous medium containing phosphoric acid, and reacting the oxidic metal compounds with elemental forms or alloys of the metals to obtain divalent metal ions, removing solid substances, producing an alkali metal phosphate receiver solution with a pH-value of 5 to 8 and metering the aqueous solution into the receiver solution and at the same time metering a basic aqueous alkali hydroxide solution that the pH-value of the resulting reaction mixture is kept in the region of 5 to 8 to precipitate the desired phosphate.
    • 通过以下方式制备磷酸盐的方法:将氧化金属(II) - ,金属(III) - 金属(FV)或具有选自氢氧化物,氧化物,氧化物 - 氢氧化物,氧化物 - 水合物,碳酸盐和氢氧化碳酸盐的混合氧化物阶段的化合物引入, 的金属Mn,Fe,Co和Ni中的至少一种与至少一种金属Mn,Fe,Co和/或Ni的元素形式或合金混合到含有磷酸的水性介质中,并使氧化金属化合物 用金属的元素形式或合金形成二价金属离子,去除固体物质,制备pH值为5〜8的碱金属磷酸盐接收溶液,并将水溶液计量到接收溶液中,同时计量 将所得反应混合物的pH值保持在5至8的范围内以沉淀所需磷酸盐的碱性碱性氢氧化碱水溶液。
