Zusammenfassung:A process for the production of an amorphous or amorphised iron(III)phosphate anhydrate or a carbon composite of amorphous or amorphised iron(III)phosphate anhydrate, characterised in that iron(III)orthophosphate of the general formula FePO4 * 2H2O or carbon composite of iron(III)orthophosphate of the general formula FePO4 * 2H2O, wherein at least 80% by weight of the iron(III)orthophosphate is present in accordance with powder X-ray diffraction analysis with CuK[alpha] radiation in the phosphosiderite (metastrengite II)-crystal structure, is dehydrated at a temperature in the region of between 140 and 250 DEG C to a residual water content of between 0 and 1% by weight, which includes both bound water of crystallisation and also free water, and to a water of crystallisation content ≤ 0.2 H2O.
