Grooved Tungsten Heater
1.What Is Grooved Tungsten Heater?
Grooved tungsten heater is a tungsten heating element formed from multi-strand high-purity tungsten wire through precision twisting and forming into a grooved structure. It enables stable evaporation of metals or functional materials through resistive heating and is suitable for granular, wire-form, or small-piece evaporation materials.
2.Features of CTIA’s Grooved Tungsten Heater
(1) Capillary retention effect: Enable capillary action within inter-strand gaps, reducing molten material flow and splash while improving evaporation stability.
(2) Uniform current distribution and thermal uniformity: Distribute current density across multiple conductive paths to minimize localized overheating and ensure stable heating performance.
(3) Mechanical stability and thermal stress resistance: Twisted-wire construction enhances structural stability and reduces deformation during repeated thermal cycling.
(4) Increased heating contact area: Multi-strand geometry increases effective heat exchange area, improving evaporation efficiency.
(5) High surface cleanliness: Chemical cleaning or electrolytic polishing reduces impurities and outgassing for high-vacuum applications.
3.Applications of CTIA’s Grooved Tungsten Heater
(1) Vacuum metallization coating: Used for aluminum and chromium evaporation in decorative plastic parts, mirrors, and mobile phone housings.
(2) Electronic component manufacturing: Used for conductive film deposition in capacitors and transistors.
(3) Semiconductor and display technology: Used as controlled evaporation source for precision thin-film deposition under vacuum environments.
(4) Laboratory micro-evaporation: Used for stable evaporation of granular or wire-form metals in research sample preparation.
