    • PURPOSE: A europium containing bismuth titanate ferroelectric material is provided, which has a high residual polarization value, a low dielectric loss property, and an excellent endurance against fatigue. CONSTITUTION: The europium containing bismuth titanate ferroelectric material represented by the formula 1 is produced by a process comprising the steps of: dissolving a europium containing compound, a bismuth containing compound, and a titanium containing compound in the molar ratio of x:4-x:3(x is 0.2-0.9) in a common solvent to prepare a precursor solution stable in the air; preparing a thin film by using the precursor solution by a spin coating method; drying and calcining the thin film. In the formula, x is 0.2-0.9.
    • 目的:提供含有铋钛酸铁铁氧体材料,其具有高残留极限值,低介电损耗特性和耐疲劳耐久性。 构成:由式1表示的含铋钛酸铁电材料的制造方法包括以下步骤:将含铕化合物,含铋化合物和含钛化合物以x:4-x :3(x为0.2-0.9)在常规溶剂中制备在空气中稳定的前体溶液; 通过旋涂法使用前体溶液制备薄膜; 干燥和煅烧薄膜。 在式中,x为0.2-0.9。
