摘要：
The dielectric properties and microstructures were investigated in ceramics of BaO.Nd2O3.5TiO2 to which various amounts of Mn were added. Although the behavior of the dielectric constant was independent of additional Mn, the temperature coefficient was improved considerably. The phases which were observed in these ceramics were characterized by means of electron probe microanalysis (EPMA) and X-ray diffraction method (XRD) in microareas. The shapes and areas of the phases varied with Mn content. The dielectric properties seemed to be mainly related to the properties of the matrix phase.
