Tungsten Boat
A tungsten boat is a container made from high-purity tungsten material, named for its boat-like shape. It features excellent high-temperature resistance, good electrical conductivity, and corrosion resistance, making it widely used in vacuum evaporation, thermal evaporation, metal sintering, and electron beam evaporation processes.
Key Features
1.High-Temperature Resistance – With a melting point of 3410°C, tungsten boats can operate stably in extreme high-temperature environments.
2.High Purity – Reduces impurities, ensuring stability under high vacuum and high-temperature conditions.
3.Excellent Thermal Conductivity – Aids in uniform heating, improving evaporation efficiency.
4.Corrosion Resistance – Resists most acids, bases, and oxidation environments, making it suitable for specialized processes.
5.High Mechanical Strength – Resistant to deformation, allowing for long-term use.
Common Types
Based on different manufacturing processes, tungsten boats can be classified into the following types:
1.Sintered Tungsten Boat – Produced using powder metallurgy, suitable for applications requiring high purity.
2.Folded Tungsten Boat – Made by folding tungsten sheets, featuring a simple production process and lower cost.
3.Stamped Tungsten Boat – Formed using stamping technology, ensuring high consistency and mass production capability.
4.Welded Tungsten Boat – Manufactured by welding tungsten plates or strips, ideal for large or specially shaped tungsten boats.
5.Riveted Tungsten Boat – Assembled using riveted joints, suitable for larger sizes or specialized structural requirements.
Applications
1.Vacuum Evaporation Coating – Used for evaporating metals such as aluminum, silver, and gold in optical coatings and electronic component manufacturing.
2.Semiconductor Industry – Applied in processes such as Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) in semiconductor chip fabrication.
3.Metal Sintering – Used in powder metallurgy, sintering of refractory metals, and high-temperature annealing treatments.
4.Laboratory & Research – Employed in high-temperature material studies and thermal evaporation experiments.
