Abstract
Textured Li0.95Nb0.45Ti0.7O3 (LNT) microwave dielectric ceramics were fabricated by the screen-printing templated grain growth technique (sp-TGG). The plate-like LNT particles with diameters of 5–20 μm and thicknesses of 0.5–2.0 μm prepared by molten salt synthesis (MSS) were chosen as templates. The <110> oriented LNT ceramics with an orientation degree of 73% were fabricated via the sp-TGG method. The dielectric anisotropy was observed in LNT(//) and LNT(⊥) samples. At microwave frequency, the LNT(//) sample exhibits ϵ r = 47, Q×f = 9893 GHz, τ f = −18 ppm/°C, whereas the LNT(⊥) sample exhibits ϵ r = 75, Q×f = 6942 GHz, τ f = 52 ppm/°C.
