Chemical compound

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 Fe to Fe. Ferberite is composed of this compound.

Synthesis techniques

Hydrothermal process

The hydrothermal process is a method for synthesizing FeWO 4 {\displaystyle {\ce {FeWO4}}} crystals. Reagents used in this process are: - Ethylenediamine tetraacetic acid disodium salt ( Na 2 EDTA ) {\displaystyle {\ce {(Na2EDTA)}}} and Hexamethylenetetramine ( HMT ) {\displaystyle {\ce {(HMT)}}} . Na 2 EDTA {\displaystyle {\ce {Na2EDTA}}} helps in controlling the morphology of FeWO 4 {\displaystyle {\ce {FeWO4}}} crystals by binding to metal ions and preventing their premature precipitation and HMT {\displaystyle {\ce {HMT}}} acts as a pH buffer and a source of ammonia.
