U-Type Tungsten Heater
What’s U-Type Tungsten Heater?
U-type tungsten heater, known as U-shaped tungsten heater, is a high-temperature resistance heating element manufactured from high-purity tungsten wire or stranded tungsten wire through precision bending into a U-shaped configuration. It is primarily utilized for continuous vaporization and thin-film deposition of metallic materials.
Characteristics of CTIA’s U-Type Tungsten Heater
(1) Highly concentrated heating zone: U-shaped bending configurations create a stable high-temperature core, focusing thermal energy precisely at critical evaporation zones to accelerate thermal response.
(2) Stable vacuum compatibility: Capable of reliable long-term operation within vacuum environments ranging from 10⁻³ Pa to 10⁻⁶ Pa or inert gas atmospheres, ensuring exceptional evaporation stability.
(3) Structural retention at elevated temperatures: Tungsten maintains excellent mechanical stability at temperatures exceeding 2,000°C, remaining highly resistant to noticeable deformation.
(4) Clean evaporation environment: Low vapor pressure minimize material volatilization, preserving thin-film purity and chamber cleanliness.
Applications of CTIA’s U-Type Tungsten Heater
(1) Vacuum evaporation coating: Serving as reliable evaporation sources for metals such as aluminum, silver, copper, and chromium.
(2) Optical coatings: Production of anti-reflective films, reflective coatings, and precision optical thin films.
(3) Consumer electronics: Housing metallization and decorative coating processes.
(4) Semiconductor processing: Deposition of electrode materials and functional thin-film fabrication.
(5) Laboratory vacuum systems: Material evaporation research and thermal process development.
