Formula: Au 88/Ge 12
Form: Pellet/Lump
Material: Gold/Germanium Eutectic Alloy
Commodity: Precious Metals
Maximum Lump Size:
10mm
Gold/germanium eutectic alloy pellets (Au88/Ge12) are part of Goodfellow's range of pellets. These pellets are commonly used in semiconductor research where precise casting temperatures are required. With their defined melting point and excellent conductivity, the gold/germanium pellets are ideal for applications needing precise temperature control and heat dissipation.
