We researched about a bulk metallic glass system as an additive to an Ag paste for high temperature thermoelectric modules. Bulk metallic glass (BMG) ribbons were produced by using a rapid solidification process (RSP) under a cooling rate condition higher than 10℃/sec. We investigated BMG characteristics of the ribbons by means of x-ray diffraction (XRD) and differential scanning calorimetry (DSC) in order to evaluate the glass transition temperature (Tg) and the recrystallization temperature (Tx) lower than 400℃. A milling process was also developed to apply the BMG ribbons to a commercial Al paste as an additive for lower sintering temperature.
