LaB6

LaB6 single crystal (Lanthanum Hexaboride) is a material with excellent electron emission properties and high heat resistance. It is mainly used as an electron source or cathode material and is widely used in electron microscopes, discharge devices, etc.

Features
　●Low work function LaB6's low work function allows for efficient electron emission, which is higher than other cathode materials such as tungsten​
　●High electron
     emission efficiency		 LaB6 is approximately 10 times brighter and more durable than tungsten filaments, and is used in devices that require high precision, such as electron microscopes and electron beam lithography.
