Product Description:
Lanthanum hexaboride is widely used as a high-performance electron emitter in electron microscopes and other electron beam instruments due to its low work function and high thermal stability. Its ability to produce a bright and stable electron beam makes it ideal for applications requiring high-resolution imaging and analysis. Additionally, it is employed in the manufacturing of cathodes for plasma displays and in specialized vacuum electronics. In the field of materials science, lanthanum hexaboride is utilized in high-temperature environments, such as in crucibles for single crystal growth, owing to its excellent thermal and chemical resistance. It also finds use in coatings for components exposed to extreme conditions, enhancing durability and performance.
