Abstract
The low sintering temperature and the good dielectric properties such as high dielectric constant (ε r ), high quality factor (Q × f), and small temperature coefficient of resonant frequency (TCF) are required for the application of chip passive components in wireless communication low temperature co-fired ceramics (LTCC). In the present study, the sintering behaviors and dielectric properties of Ba3Ti5Nb 6O28 ceramics were investigated as a function of B 2O3-CuO content. The pure Ba3Ti 5Nb6O28 system showed a high sintering temperature (1250°C) and had the good microwave dielectric properties: Q × f of 10,600 GHz, ε r of 37, TCF of -12 ppm/°C. The addition of B2O3-CuO was revealed to lower the sintering temperature of Ba3Ti5Nb6O28, 900°C and to enhance the microwave dielectric properties: Q × f of 32,500 GHz, ε r of 40, TCF of 9 ppm/°C. From the X-ray photoelectron spectroscopy (XPS) and X-ray powder diffraction (XRD) studies, these phenomena were explained in terms of the reduction of oxygen vacancies and the formation of secondary phases having the good microwave dielectric properties.
