“…4,5 Since Kagata et al 6 reported the microwave dielectric properties of BiNbO 4 with sintering aids, various attempts have been undertaken to improve the microwave dielectric properties of BiNbO 4 , such as the substitution of lanthanide for Bi, 7-9 the solid solutions of Bi(Nb 1−x Ta x )O 4 , 10 Bi(Nb 1−x Sb x )O 4 11 and the addition of various sintering aids. 12,13 Also, the ABO 4 (A Bi 3+ ,Sb 3+ , B Nb 5+ ,Ta 5+ ,Sb 5+ ) compounds with stibiotantalite structure are known to exhibit multiple structural and dielectric phase transitions.…”

“…The relative density slightly decreased when CuO addition exceeded 2.0 mol%, possibly due to the increased liquid phase and second phase [46]. While in BiNbO 4 ceramics, Huang et al [47] reported that 0.25-1 wt.% CuO is suitable to obtain dense pellets and 2 wt.% resulted in a lower density.…”

“…In 2001 Huang [12] investigated the behaviour and the microwave dielectric properties of BiNb (1-x) Ta x O 4 doped with CuO. The powders were prepared by the solid-state reaction method, and the dielectric measurements, in the frequency range of 6-8 GHz, were performed using the Hakki-Coleman's technique.…”

The development of new dielectric materials that allow the reduction of size and weight of electronic components has been in the scope of the researchers. The bismuth-based dielectric ceramics are extensively studied for this purpose, namely, the bismuth niobate (BiNbO 4). The first attempt to improve BiNbO 4 occurred in 1992 when Kagata reported the microwave dielectric properties of bismuth niobate doped with the addition of oxides. This chapter will present a brief review of the several attempts that have been carried out to enhance the dielectric properties of BiNbO 4 by modifying their structure through addition, doping, or atom(s) substitution. This manuscript focuses on a case study that involves bismuth substitution by europium ions. To investigate the inclusion of europium in BiNbO 4 ceramics, (Bi 1-x Eu x)NbO 4 samples were prepared using the sol-gel method, in particular, the citrate route. The structure of the prepared samples was studied by X-ray diffraction (XRD) and Raman spectroscopy and the morphology by scanning electron microscopy (SEM). The dielectric properties were studied, in the microwave frequency range (MW), using the resonant cavity method, and in the radio frequency range (RF), with the impedance spectroscopy technique.
