Vacuum-degassed 5N (99.999%) / 6N Zone-Refined germanium (Ge, CAS 7440-56-4) evaporation pellets, granules, and slugs engineered for spit-free electron-beam and resistive thermal PVD.
Prepared specifically for high-vacuum electron-beam and resistive thermal evaporation, our 5N (99.999%) / 6N Zone-Refined germanium (Ge, CAS 7440-56-4) deposition materials undergo vacuum degassing or high-temperature sintering to eliminate trapped volatiles and micro-voids that cause melt spitting and pinhole film defects.
Use graphite, vitreous carbon, or quartz/alumina e-beam liners, or tungsten/tantalum/alumina-coated resistive boats. Supplied in cleanroom argon-flushed containers by weight (50 g to 1,000 g lots) or piece count, accompanied by the manufacturer's batch trace-impurity Certificate of Analysis.
