PROCESS FOR PRODUCTION OF PHOSPHORIC ACID COMPOUND, AND PROCESS FOR PRODUCTION OF SECONDARY BATTERY

It is to provide a process for producing a phosphate compound capable of producing olivine-type crystalline particles of a phosphate compound excellent in the properties and the reliability, easily at a low cost. Particularly, it is to provide a process for producing a phosphate compound useful as a cathode material for a secondary battery. [0002] Solid particles of a compound (Y) having a composition represented by AMPO(wherein the element A is at least one member selected from the group consisting of Li and Na, the element M is at least one member selected from the group consisting of Fe, Mn, Co and Ni, the valency N of the element M satisfies +2
