<p>A method for manufacturing a silicate compound having a composition represented by formula (B). In said method, said silicate compound is manufactured by performing the following steps in order: a step wherein a melt is obtained by heating a feedstock mixture, obtained by controlling a feedstock containing atomic A, atomic M, silicon, phosphorus, and E such that the molar proportions of said atomic A, atomic M, silicon, phosphorus, and E equal the molar proportions indicated by formula (B); a cooling step wherein a solidified material is obtained by cooling the aforementioned melt; a pulverization step wherein a pulverized material is obtained by pulverizing said solidified material; and a heating step wherein the abovementioned silicate compound is obtained by heating said pulverized material. (B) A f M b Si1- x - y P x E y O g2 (In the formula, A represents at least one element selected from a group comprising lithium, sodium, and potassium; M represents at least one element selected from a group comprising iron, manganese, cobalt, and nickel; E represents either aluminum or aluminum and boron; f satisfies 0.8 f b satisfies 0.7 = b = 1.3; x satisfies 0 x y satisfies 0 y x and y satisfy 0 x+y) = 0.7, and g2 represents a number that depends on f, b, x, y, and the valence (N) of M.)</p> |
