CTIA's Tungsten Heater in Rare Metal Evaporation
CTIA’s tungsten heater is a heating component used in vacuum evaporation processes for rare metals and their alloys, enabling controlled heating, melting, evaporation, and deposition. The tungsten heating element is widely applied in precision optical coating, semiconductor conductive layer fabrication, high-end jewelry vacuum coating, and laboratory material research.
Manufactured from high-purity tungsten wire or doped tungsten wire through precision stranding, coiling, forming, and surface cleaning processes, the tungsten heater serves as a stable heat source under high vacuum and high-temperature conditions. It enables uniform evaporation of rare metals such as gold, silver, platinum, and palladium, forming dense and uniform functional thin films on substrate surfaces.
