China Factory 99.95% Lanthanum Hexaboride for Reasonable Price

Application 

It has been successfully used in more than 20 military and high-tech fields such as radar aerospace, electronic industry, instrumentation, medical equipment, home appliances, metallurgy, environmental protection and so on. 1) Electron emission cathode. Due to the low electron escape work, cathode materials with the highest emission current at medium temperature can be obtained, especially high-quality single crystals, which are ideal materials for high-power electron emission cathodes. 2) High brightness point light source. For the preparation of core components of electron microscopy, such as selective optical filters, soft X-ray diffraction monochromators, and other electron-beam light sources. 3) High stability and long life system components. The excellent comprehensive performance makes it used in various electron beam systems, such as electron beam engraving, electron beam heat source, electron beam welding gun and accelerator engineering fields for making high performance components.
