It was discovered in the 1960s in Donetsk Oblast in Soviet Union, and named '''fersilicite''', but was not approved by the International Mineralogical Association. It was later rediscovered in the Nagqu area of Tibet and given the name naquite. Naquite occurs together with other rare iron silicide minerals, xifengite (Fe<sub>5</sub>Si<sub>3</sub>) and linzhiite (FeSi<sub>2</sub>).<ref name=webmin/>
