METAL PHOSPHATES AND METHOD OF PRODUCING THEM Russian patent published in 2017 - IPC C01B25/37 C01B25/45 H01M4/58 

FIELD: chemistry.

SUBSTANCE: invention relates to monophosphates or mixed metallic phosphate of type (M1, M2, M3, …Mx)₃(PO₄)₂⋅aH₂O, where 0≤a≤9, and process to obtain them. In this case (M1, M2, M3, …Mx) are metal monophosphates metal or several metals in the mixed metallic phosphates and metals are selected from 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 provided that at least one metal in phosphate is selected from Mn , Fe, Co and Ni, wherein the phosphate comprises no more than 10 different metals M1, M2, M3, …Mx.

EFFECT: invention is used to prepare the lithiated (containing Li) cathode material for Li-ion batteries and phosphates with high purity.
