V-Type Tungsten Heater
1. What Is V-Type Tungsten Heater?
V-type tungsten heater is a precision tungsten heating element engineered for vacuum evaporation processes. It features a geometrically defined V-shaped structure designed to localize the evaporation zone. This configuration utilizes gravity and surface tension to stabilize molten materials within the groove base, preventing material migration during high-temperature operation.
2.Features of CTIA’s V-Type Tungsten Heater
(1) Extreme Thermal Stability: Utilize tungsten’s high melting point of 3420°C to ensure structural stability under high vacuum and severe thermal loads, preventing deformation and operational failure.
(2) Enhanced Creep Resistance: Fabricated using high-purity tungsten wire or doped tungsten wire grades HW41 and HW42 with improved recrystallized grain structure for enhanced creep resistance and extended service life.
(3) Precise Thermal Field Control: Maintain stable electrical resistance and low thermal expansion to enable uniform heat distribution and consistent thin-film deposition quality.
(4) Point-Source Evaporation Accuracy: Provide a defined material holding zone for evaporation from a fixed geometric center to ensure precise film thickness control.
(5) Optimized Energy Efficiency: Concentrate current density at structural vertices to reduce ignition power requirements and improve evaporation efficiency and material utilization.
(6) Mechanical Durability: Construct from single or multi-strand high-purity tungsten wire to maintain geometric stability under repeated thermal cycling across electrode configurations.
3.Applications of CTIA’s V-Type Tungsten Heater
(1) Industrial Surface Coating: Used for vacuum metallization of mirrors, solar collector tubes, plastic components, and decorative parts.
(2) Electronic Device Manufacturing: Serves as a heating element in cathodes of electron tubes and supports thermal processes in semiconductor components.
(3) Laboratory Sample Preparation: Used in Scanning Electron Microscope (SEM) sample gold coating preparation, ensuring consistent deposition rates for research applications.
(4) Metal Substrate Enhancement: Used to deposit functional thin films on metal substrates to improve adhesion and surface performance.
