将超细亚微米尺寸的BaCO 3粉末和TiO 2（金红石）粉末的混合物在空气中在700°C、800°C和900°C下煅烧，然后在每种情况下骤冷至液氮温度。横截面淬火试样，其特征在于空间分辨电子能量损失谱（SR-EELS）。能量损失近边结构（ELNES）依次提取在1.3至5.3 nm的宽度从SR-EELS图像从矩形切割SR-EELS狭缝孔径放在合成的钛酸钡层和TiO 2金红石粉末。Ti-L2，3边和Ba-M4，5边的ELNES清楚地显示了从BaTiO 3层表面到TiO 2体区域的精细结构变化，这反映在合成的BaTiO 3的结晶度、Ba扩散引起的TiO 2的晶格畸变以及BaTiO 3和TiO 2之间的晶格失配，而没有形成Ba 2 TiO 4和其他钛酸盐相。
A mixture of ultrafine submicrometer-sized BaCO3 powder and TiO2 (rutile) powder was calcined in air at 700°C, 800°C, and 900°C, and then quenched to liquid nitrogen temperature in each case. The cross-sectional quenched specimens were characterized by spatially resolved electron energy-loss spectroscopy (SR-EELS). The energy-loss near-edge structures (ELNES) were sequentially extracted at 1.3 to 5.3 nm in width from SR-EELS image obtained from the rectangularly cut SR-EELS slit aperture put on the synthesized BaTiO3 layer and TiO2 rutile powder. The ELNES of Ti-L2,3 edges and Ba-M4,5 edges clearly show fine structure changes from the surface of BaTiO3 layer to the TiO2 bulk region reflected from crystallinity of synthesized BaTiO3, lattice distortion of TiO2 caused by Ba diffusion, and lattice misfit between BaTiO3 and TiO2 without formation of Ba2TiO4 and other titanate phases.
