Abstract: The dependence of microwave dielectric properties on the isovalent substitution of (Sn1/24+W1/26+)5+ (electronegativity difference from O2−, X = 2.16) and (Ti1/24+W1/26+)5+ (X = 1.95), with higher electronegativity differences than Nb5+ (X = 1.6) at Nb5+-sites of Mg4Nb2O9 ceramics was investigated.
