Chemical compound

Ferrous tungstate (FeWO₄) 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 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]
