Vacuum-degassed 4N5 (99.995%) Vacuum-Grown Crystal Optical Grade magnesium fluoride (MgF2, CAS 7783-40-6) 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%) Vacuum-Grown Crystal Optical Grade magnesium fluoride (MgF2, CAS 7783-40-6) deposition materials undergo vacuum degassing or high-temperature sintering to eliminate trapped volatiles and micro-voids that cause melt spitting and pinhole film defects.
Evaporates cleanly from molybdenum or tantalum resistive boats as well as molybdenum/graphite e-beam pocket liners with minimal dissociation. 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.
