Vacuum-degassed 4N5 (99.995%) CVD Optical Grade zinc sulfide & zinc selenide (ZnS / ZnSe, CAS 1314-98-3) 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 4N5 (99.995%) CVD Optical Grade zinc sulfide & zinc selenide (ZnS / ZnSe, CAS 1314-98-3) deposition materials undergo vacuum degassing or high-temperature sintering to eliminate trapped volatiles and micro-voids that cause melt spitting and pinhole film defects.
Sublimes congruently without liquid melting; use baffled tantalum/molybdenum resistive box sources or quartz/graphite liners to prevent spatter. 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.
