Abstract

¹H and ¹³C Fourier transform-nuclear magnetic resonance (FT-NMR) and mass spectrometric (MS) techniques were used to prove the structures of precursors used in the sol-gel synthesis of the high-frequency dielectric Ba(Mg_1/3Ta_2/3)O₃. Various metal methoxyethoxides (MEO) of Ba, Ta, Mg-Ta and Ba-Mg-Ta systems were prepared in 2-methoxyethanol (MeOEtOH). The tantalum and the magnesium-tantalum precursors were determined to be Ta₂(MEO)₁₀ and MgTa₂(MEO)₁₂, respectively. Similar spectroscopic studies for 'Ba₃MgTa₂(MEO)₁₅' indicated that the Ba-Mg-Ta alkoxide precursor has a polymer structure of (Ba,Mg,Ta)(MEO) complex and contains the bridging alkoxy groups between Ta and the alkaline earth metals.
