A method for manufacturing a silicate-phosphate compound, said method providing increased control over composition and particle size. After a solidified material is obtained by cooling a molten material represented by A1+ x + a M b Si x P1- x O4+ c1 (wherein A represents at least one element selected from the group comprising lithium, sodium, and potassium; M represents at least one element selected from the group comprising iron, manganese, cobalt, and nickel; a satisfies -0.1 = a = 0.4; b satisfies 0.7 = b = 1.3; x satisfies 0.3 = x c1 is a number that depends on a, b, and the valence (N) of M and becomes c2 after a heating step), a pulverized material is obtained by pulverizing said solidified material. A silicate-phosphate compound having a composition represented by A1+ x + a M b Si x P1- x O4+ c2 (wherein A, M, a, b, and x have the same meanings as above, and c2 is a number that depends on a, b, and the valence (N) of M) is manufactured by heating the pulverized material. |
