Abstract
Relationships between structural characteristics and microwave dielectric properties of ATiO3 (A = Ni, Mg, Co, Mn) with ilmenite structure were investigated. The oxygen octahedral distortion was dependent on the type of A-site ions which affected to the temperature coefficient of the resonant frequency (TCF) of ATiO3 ceramics. The quality factor (Qf) of ATiO3 (A = Mn, Ni, Co) specimens was appreciably lowered than that of MgTiO3 specimens due to the degree of covalency of cation–oxygen ion bond and the ordering of A-site ions. Also, the dielectric constant (K) was dependent on the electronic oxide polarizabilities of ATiO3 ceramics.
