Description
Summary:The characterisation and preparation of a glass composition in the CaO-Al2O3-SiO2 phase diagram with a judicious choice of fluxes that met all the dielectric, electrical, and thermal property requirements for low-temperature cofired ceramic (LTCC) applications are reported. The glass composition sintered at 900 C attained good density (2.45 g/cm3) and did not precipitate any crystalline phase. However, when this glass powder was sintered at the same temperature in the presence of 30 vol% cordierite, crystallisation of the anorthite phase was observed, which improved the properties of the composite for LTCC applications. 27 refs.
