Synthesis, characterization and properties of [RE1−xREx′]TiNbO6 dielectric ceramics

Effect of WO3 and MoO3 addition on LnTiTaO6 (Ln=Ce, Pr and Nd) microwave ceramics

“…All the samples are found to be well sintered with minimum porosity. The grain morphologies of all the doped samples are found to be similar that of the grains of aeschynite structured ceramics [33,34]. However, there are grains of secondary phases, which is in accordance with the XRD patterns.…”

Fabrication and characterization of xPrTiTaO6(1−x)YTiNbO6 microwave ceramic composites

“…They found that, in rareearth titanium niobate system, members of the aeschynite group have positive f with high dielectric constant, whereas euxenites have negative f with low dielectric constant. Sam Solomon et al [4] reported that the solid solution phases between the aeschynite and the euxenite groups possess intermediate dielectric constant and f values. Reaney and Iddles [5] in 2006 mentioned the creation of a solid solution or composite of two materials, each having opposite signs of f .…”

Synthesis, characterization and properties of Ln(Ti0.8Sn0.2)TaO6 (Ln=Nd, Sm) microwave ceramics

“…Attempts were made to obtain desirable microwave dielectric properties by suitable substitution and doping in LnTiTaO 6 ceramics. Surendran et al [6], Solomon et al [7], Oishi et al [8,9] and Padma Kumar et al [10][11][12] have studied the substitutional effects of lanthanides in the A site. The f was reduced to zero approximately without much compromise in the values of the ε r and quality factor by these substitutions.…”
