Ferrous tungstate

(Redirected from Iron(II) tungstate)

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

Hydrothermal process

edit

The hydrothermal process[definition needed] is a method for synthesizing   crystals. Reagents used in this process are: - Ethylenediamine tetraacetic acid disodium salt  and Hexamethylenetetramine  .   helps in controlling the morphology of   crystals by binding to metal ions and preventing their premature precipitation and   acts as a pH buffer and a source of ammonia.[3]
