Molybdenum Wire for Vacuum Coating
Molybdenum wire for vacuum coating is a high-purity metallic wire specifically developed for use in vacuum deposition technologies, such as thermal evaporation and electron beam evaporation. Thanks to its excellent thermal stability, electrical conductivity, and resistance to chemical reactions under high-vacuum conditions, it plays a critical role as a heating or supporting element in various thin-film deposition processes.
Key Characteristics
1.High Melting Point: Molybdenum has a melting point of approximately 2620°C, making the wire suitable for high-temperature vacuum environments.
2.Excellent Thermal and Electrical Conductivity: Ensures efficient heating and stable performance during evaporation or sputtering.
3.Low Vapor Pressure: Maintains material integrity under high vacuum without contaminating the coating environment.
4.Good Mechanical Strength: Resists deformation and breakage under thermal stress, ensuring longevity and consistency in performance.
5.High Purity: Typically >99.95%, minimizing impurities that could affect film quality or process stability.
