      Given the importance of tungstate in industry and aiming to introduce new tungstate nanostructure with a modern method, iron tungsten nanofibres were prepared for the first time by sol–gel followed by electrospinning andcalcination. First, poly(vinyl alcohol) (PVA) as a matrix polymer was mixed separately with tungstic acid (H$_2$WO$_4$) and iron(III) nitrate (Fe(NO$_3$)$_3$). The controlled mixing of the two solutions followed by electrospinning led to the fabrication of PVA/tungstic acid/iron(III) nitrate composite nanofibres. Finally, ceramic nanofibres of iron tungstate were obtainedfrom the calcination of polymeric nanofibres under thermal control conditions. The final product was analysed by scanning electron microscopy, energy-dispersive X-ray spectroscope, Fourier transform infrared spectroscopy, X-raydiffraction, vibrating sample magnetometer, Brunauer–Emmett–Teller surface area analysis and Barrett–Joyner–Halenda pore size and volume analysis.
