Microwave Dielectric Properties of the Binary System BiNbO4–FeNbO4

“…The dielectric properties of bismuth-based lead-free compounds, including bismuth zinc niobate, bismuth zinc tantalate, bismuth copper niobate, bismuth magnesium niobate and bismuth iron niobate have been studied, with promising results. [11][12][13][14][15][16] In particular, the substitution of bismuth by iron, lead to a significant increase of the dielectric constant. 15 Given these previous results and since the main advantage of composites is the ability to tailor materials physical properties for special purposes, the BiNbO 4 -FeNbO 4 binary was developed.…”
