Lanthanum Hexaboride Rod, LaB6 Rod
Lanthanum hexaboride (LaB6) rods are cylindrical shaped components made from a rare earth material with a hexagonal crystal structure. LaB6 rods are widely used in electron microscopy as a cathode material due to their high electron emission properties. They are also used as a thermionic source for electron beam melting, welding, and vapor deposition processes.
LaB6 rods are available in various sizes and can be machined to specific dimensions as per the requirements of the application. They exhibit high hardness and resistance to corrosion and oxidation, making them suitable for use in high-temperature environments. In addition, LaB6 rods have a low work function, which allows them to emit electrons at relatively low temperatures, leading to energy savings and longer service life.
