| 中文摘要 | the novel nano-ultrafine powders for the preparation of cacu3ti4o12 ceramic were prepared by the sol-gel method and citrate auto-ignition method. the obtained precursor powders were pressed, sintered at 1000 degrees c to fabricate microcrystal cacu3ti4o12 ceramic. the microcrystalline phase of cacu3ti4o12 was confirmed by x-ray powder diffraction (xrd). the morphology and size of the grains of the powders and ceramics under different heat treatments were observed using scanning electron microscopy (sem). the relative dielectric constant of the ceramic sintered at 1000 degrees c was measured with a magnitude of more than 10(4) at room temperature, which was approaching to those of pb-containing complex perovskite ceramics, and the loss tangent was less than 0.20 in a broad frequency region. the relative dielectric constant and loss tangent were also compared with that of cacu3ti4o12 ceramic prepared by other reported methods.
