Ferrous tungstate () is an inorganic compound, a tungstate of ferrous iron. It occurs naturally as ferberite.
Synthesis It can be synthesized from iron(III) chloride and sodium tungstate under hydrothermal conditions where the presence of L-cysteine reduces Fe3+ to Fe2+.
crystals can be prepared by hydrothermal synthesis. Reagents used in this process are ethylenediaminetetraacetic acid disodium salt () and hexamethylenetetramine (HMT). helps in controlling the morphology of crystals by binding to metal ions and preventing their premature precipitation and HMT acts as a pH buffer and a source of ammonia.
