Ferrous tungstate (FeWO
4) is an inorganic compound, a tungstate of ferrous iron. It can be synthesized from iron(III) chloride and sodium tungstate under hydrothermal conditions with the presence of L-cysteine reduces Fe3+ to Fe2+.[1] Ferberite is composed of this compound.[2]
Synthesis techniques
Hydrothermal process
The hydrothermal process[definition needed] is a method for synthesizing FeWO
4 crystals. Reagents used in this process are ethylenediaminetetraacetic acid disodium salt (Na
2EDTA) and hexamethylenetetramine (HMT). Na
2EDTA helps in controlling the morphology of FeWO
4 crystals by binding to metal ions and preventing their premature precipitation and HMT acts as a pH buffer and a source of ammonia.[3]
