Ferrous tungstate (FeWO4) is an inorganic compound. 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
[edit]Hydrothermal process
[edit]The hydrothermal process[definition needed] is a method for synthesizing FeWO4 crystals. Reagents used in this process are ethylenediaminetetraacetic acid disodium salt (Na2EDTA) and hexamethylenetetramine (HMT). Na2EDTA helps in controlling the morphology of FeWO4 crystals by binding to metal ions and preventing their premature precipitation and HMT acts as a pH buffer and a source of ammonia.[3]
