Conical Tungsten Heater
What’s Conical Tungsten Heater?
Conical tungsten heater is a high-temperature resistance heating element manufactured from high-purity tungsten wire wound into a tapered conical configuration for metal evaporation and thermal field control within vacuum coating systems.
Characteristics of CTIA’s Conical Tungsten Heater
(1) Conical heat concentration: Heat concentrates from the base toward the top, creating a stable high-temperature core zone.
(2) High evaporation adaptability: Suited for stable evaporation of granular or bulk metallic materials.
(3) High-temperature stability: With a melting point around 3,422°C, tungsten maintains structural integrity at temperatures exceeding 2,000°C.
(4) Low contamination: Extremely low vapor pressure under high vacuum minimizes material volatilization contamination.
(5) Stable operation: Consistent central hot zone makes it ideal for continuous evaporation operating conditions.
(6) Thermal stress resistance: Tapered design minimizes localized stress concentration, lowering deformation risks.
