Lanthanum Hexaboride Tube, LaB6 Tube
Lanthanum hexaboride (LaB6) tube is a ceramic component made from the rare-earth boride compound. It has excellent thermal and electrical conductivity, high melting point, and high hardness, making it suitable for various high-temperature applications. LaB6 tube is commonly used in electron beam applications as a cathode filament material, where it can emit electrons at high temperatures due to its low work function. It can also be used in vacuum deposition, sputtering, and plasma applications due to its resistance to corrosion and erosion at high temperatures. LaB6 tube is available in various sizes and can be customized according to specific requirements.
