Tungsten needle for vacuum equipment refers to a slender tool used in a vacuum environment. Its manufacturing material is tungsten or tungsten alloy. Tungsten needles for vacuum equipment usually have high temperature stability, high melting point and corrosion resistance, making them suitable for some special vacuum systems and applications.
The following are some characteristics and applications of tungsten needles for vacuum equipment:
1. Low vapor pressure: Tungsten has a relatively low vapor pressure, so when used under vacuum conditions, it is not easy to evaporate or release gas, which is beneficial to maintaining a high vacuum environment.
2. High melting point: The high melting point of tungsten enables it to work in high temperature environments without failure. In vacuum equipment, some components may be affected by higher temperatures, so it is important to use high melting point materials.
3. Corrosion resistance: Tungsten needles usually show good corrosion resistance, which is important to prevent oxidation and corrosion in some vacuum environments.
4. Vacuum electronic devices: Tungsten needles for vacuum equipment are often used as electron emission sources in vacuum electronic devices, such as cathodes and anodes. Tungsten is a common material choice due to its electron-emitting properties and stability in high vacuum.
5. Optical thin film deposition: In some optical and thin film deposition applications, tungsten needles for vacuum equipment may be used to support or transfer materials.
Overall, tungsten needles for vacuum equipment are tools that perform well in high vacuum environments and are suitable for a range of specialized applications, including vacuum electronics, optical thin film deposition, and more.
