N2 - Low temperature co-fired ceramic (LTCC) is prepared by sintering a glass selected from CaO-SiO2-B2O3 system, and its sintered bodies are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). It is found that the optimal sintering temperature for this glass-ceramic is 820 °C for 15 min, and the major phases of this material are CaSiO3, CaB2O4 and SiO2. The glass-ceramic possesses excellent dielectric properties: εr = 6.5, tan δ < 2 × 10-3 at 10 MHz, temperature coefficient of dielectric constant about -51 × 10-6 °C-1 and coefficient of thermal expansion about 8 × 10-6 °C-1 at 20-400 °C. Thus, this material is supposed to be suitable for the tape casting process and be compatible with Ag electrode, which could be used as the LTCC materials for the application in wireless communications.
