What are the Applications of Lanthanum Boride

LaB6 as cathode material has superior performance because of its high emission current density and low evaporation rate at high temperature. It has gradually replaced some tungsten cathodes in industrial applications. At present, the main application fields of six lanthanum borate LaB6 cathode materials are as follows:

New high-definition, high-current-emittance display and imaging devices, electron beam lasers and other high-tech industries are required in the fields of military and space technology, such as microwave vacuum electronic devices and ion thrusters, civil and military industries. In these high-tech industries, the demand for cathode materials with low temperature, high uniform emission, high current emission density and long life has been very tight.

Electron beam welding industry, with the development of economy, needs electron beam welding machine, electron beam smelting, cutting equipment cathode can meet the requirements of high current density, low escape power, and the traditional equipment is mainly using tungsten cathode (escape power is too high, current emission density is too small) can not meet the application requirements, and then

LaB6 cathode to Its superior performance has replaced tungsten cathode and has been widely applied in the electron beam welding industry.

High-tech instrumentation industry, LaB6 cathode has replaced tungsten cathode and other traditional hot cathode materials in electron microscope, Auger spectrometer, electron probe and other electronic devices by its high brightness, long life and other characteristics.

In accelerator industry, the stability of LaB6 against ion bombardment is higher than that of

conventional tungsten and

tantalum. LaB6 cathode is widely used in synchrotrons, cyclotrons and other accelerators with different structures.

In discharge tube industry, A.N. Broers and others have successfully realized the application of LaB6 cathode in gas discharge tube, laser tube and magnetron type amplifier.

Lanthanum boride LaB6, as an electronic component in modern technology, is widely used in civil and defense industries.

Electron emission cathode 

Because of the low electron escape power, cathode materials with the highest emission current at medium temperature can be obtained, especially high quality single crystal, which is an ideal material for high power electron emission cathode.

High brightness point light source

Core components used to fabricate electron microscopes, such as optic filters, soft X-ray diffraction monochromators, and other electron beam sources.

High stability and high life system components

Its excellent comprehensive properties make it possible to be used in various electron beam systems, such as electron beam engraving, electron beam heat source, electron beam welding torch and accelerator, etc. for the fabrication of high performance components.
