摘要: We use the rapid hot-pressing method to bond Ag foil onto pure PbTe in order assess its effectiveness as a bonding layer material for thermoelectric module applications. Scanning electron microscopy and X-ray diffraction are employed examine intermetallic compound formation microstructure evolution during isothermal aging at 400 °C 550 °C. find that is promising modules operating T_(Hot) ⩽ Additionally, our approach highlights highly effective inexpensive metallize prior assembly.
