Effects of NdAlO_3 Additives on the Properties of Ceramics
Source abstract
Abstract
The effects of NdAlO3 additives on the microstructure and the dielectric properties of Ba4.2Nd9.2Ti18O54 (BNT) materials were investigated. The microstructure of BNT doped with NdAlO3 was analyzed by X-ray diffraction and FESEM. The results show that the solid solutions are formed between Ba4.2Nd9.2Ti18O54 and the NdAlO3 additives. The relative permittivity and the TCf values show a linear decrease with the increase of NdAlO3 additive. The Q values exhibit a non-linear behaviour and reach maximum (11400GHz) for the NdAlO3 additive at approximately 10wt%, while the relative permittivity and the TCf values are 66.29 (3.5GHz) and -0.7ppm/℃, respectively.
