摘要

The crystallization and sintering behaviors of glass-ceramics (Nd 2O3-TiO2-SiO2) have been investigated using the differential thermal analyzer, thermal mechanical analyzer, X-ray diffractometer, scanning electron microscopy, and transmission electron microscopy. The results showed that the onset of glass shrinkage occurred at around the glass transition temperature (Tg=708°C). The first crystalline phase, Nd2Ti4O11, was observed at around 775°C. Fully densified NdTiSi glass can be obtained via glass viscous flow before the second crystalline phase, Nd 0.66TiO3, occurring at about 850°C. The as-prepared NdTiSi glass-ceramics sintered at 900°C exhibited a high dielectric constant of 23 and a quality factor of about 600, which provided a promising candidate for low-temperature cofired ceramics applications.
