Microwave Dielectric Properties of Eu₄Ti₃O₁₂ Ceramics via Sol-Gel Method

Abstract:

Ceramic powders with chemical formula Eu₄Ti₃O₁₂ were fabricated by sol-gel method. A milk-white homogeneously mixed gel was prepared, and transferred into a porous resin intermediate through charring. Eu₄Ti₃O₁₂ powders were prepared by calcination of the resin intermediate, and ceramic samples with two phases of Eu₂TiO₅ and Eu₂Ti₂O₇ were got by sintering. Meanwhile, the crystal structure was determined by X-ray diffraction and grain character was analyzed by scanning electron microscope. Eu₄Ti₃O₁₂ ceramics has good microwave dielectric characteristics: ε_r=27.51, Q_f=9450 GHz, τ_f=211 ppm/°C.
