Synthesis of (1-x) CaTiO3-xNdAlO3 Ceramic Powder via Ethylenediaminetetraacetic Acid Precursor

摘要：

　　(1-x)CaTiO3-xNdAlO3 (CTNA) microwave dielectric ceramics have a high Q value and a low temperature coefficient of resonant frequency (τf).CTNA ceramic powder was synthesized using a polymeric precursor derived from a mixed-metal ethylenediaminetetraacetic acid (EDTA) / ethylene glycol solution.The precursors and derived oxide powders were characterized by thermogravimetric analysis and X-ray diffraction.When x =0.3,CTNA was synthesized at 900℃ for 3 h in air.Compared with that prepared by the solid-state reaction method in literatures,the CTNA (x =0.3) ceramics with better microwave properties could be obtained at lower calcination and sintering temperatures by EDTA chelating method.
