Abstract

A mixture system of MO-SiO2 (M: Ca, Sr, Ba) glass and Al2O3 crystalline powder has been investigated as a substrate material for low temperature co-fired ceramics (LTCC). This type of glass-ceramic mixture is known to be crystallized during the sintering process. We found that glass composition was strongly related with degree of crystallized anorthite phase. And it was observed that the degree of crystallization was affected by sintering condition as well as glass composition. Crystallization behavior was monitored by means of powder X-ray diffraction (XRD). The microstructure of sintered body was examined by Scanning Electron Microscopy (SEM).
