    Abstract: The invention relates to a process for converting water-soluble, condensed phosphates of the following general formula (I)M.sub.2 O(MPO.sub.3).sub.n (I)in which M stands for sodium, potassium or ammonium and n stands for a number between 4 and about 100, to granulate, wherein the pulverulent, water-soluble, condensed phosphate is thoroughly agitated and granulated in the presence of water and of a phosphate salt other than the condensed phosphate. More specifically, the condensed phosphate of general formula (I) or a mixture of the phosphate with an anhydrous or partially hydrated alkali metal phosphate is thoroughly agitated and granulated in the presence of water and an ammonium polyphosphate of the following general formula (II)H.sub.(n-m)+2 (NH.sub.4).sub.m P.sub.n O.sub.3n+1 (II)in which n stands for an integral average value of 3 to 1000, m stands for a whole number of up to n+2, and the m/n-ratio is between about 1.0 and 1.67.

    Abstract translation: 本发明涉及一种转化下列通式（I）M 2 O（MPO 3）n（I）的水溶性缩合磷酸酯的方法，其中M代表钠，钾或铵，n代表4至约 100，其中将粉末状，水溶性的缩合磷酸盐在水和磷酸盐以外的磷酸盐的存在下充分搅拌和造粒。 更具体地，将通式（I）的缩合磷酸酯或磷酸盐与无水或部分水合的碱金属磷酸盐的混合物在水和多磷酸铵的存在下充分搅拌并造粒，通式为（II）H （nm）+2（NH4）mPnO3n + 1（II）其中n表示3〜1000的积分平均值，m表示n + 2的整数，m / n比在 约1.0和1.67。

    Abstract: The invention relates to a novel solid state process for the preparation of metal-containing compounds comprising the steps i) forming a reaction mixture comprising one or more metal-containing precursor compounds and optionally one or more non-metal-containing reactants, and ii) using one or more hypophosphite-containing materials as a reducing agent; wherein one or more of the hypophosphite-containing materials is used as an agent to reduce one or more of the metal-containing precursor compounds; and further wherein the process is performed in the absence of an oxidizing atmosphere. Materials made by such a process are useful, for example, as electrode materials in alkali metal-ion battery applications.
