Claim:
1. A method for producing a fused product comprising the following steps: a) mixing raw materials so as to form a starting charge; b) performing step b1) or step b2) to melt the starting charge to obtain a liquid mass; c) cooling the liquid mass until there is complete solidification, so as to obtain a fused product in which the amount by weight of an amorphous phase is less than 80%; d) optionally, crushing and/or grinding and/or performing granulometric selection of said fused product; e) subjecting the fused product to thermal treatment at a plateau temperature less than a melting point T f) optionally, crushing and/or grinding and/or performing granulometric selection of said fused product; wherein: said fused product has a crystalline part including more than 99.3 wt % of one and the same crystalline phase of formula (Li step b1) includes melting the starting charge until the liquid mass is obtained at a temperature T step b2) includes melting the starting charge in an oxidizing environment until the liquid mass is obtained at a temperature T wherein when step b2) is performed: the LAGJXODE phase of the fused product is such that e=0, G is Fe and X is P; the element Fe is supplied to (i) more than 97% of its weight by FePO the temperature T T T
