Abstract

CaO-B2O3-SiO2 glass powders for low-temperature co-fired ceramic applications were directly prepared by high temperature spray pyrolysis. The glass powders with a spherical shape, dense structure, fine size and narrow size distribution were prepared at a temperature of 1400 °C by complete melting and quenching processes. The composition of the spray solution was well maintained in the glass powders prepared by spray pyrolysis. The glass transition temperature (Tg) and glass crystallization temperature (Tc) of the glass powders were 704 and 836 °C respectively. Melting of the glass powders prepared occurred at a temperature of 750 °C. A pellet sintered at a temperature of 900 °C had a fully-crystallized structure and dense structure. The main crystal structure of the sintered pellets was CaSiO3.
