Lanthanum Hexaboride (LaB6, also called Lanthanum Boride and LaB) is an inorganic chemical, a boride of lanthanum. As refractory ceramic material that has a melting point of 2210 °C, Lanthanum Boride is highly insoluble in water and hydrochloric acid, and converts to the oxide when heated (calcined). Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6.07) are blue. Lanthanum Hexaboride (LaB6) is known for its hardness, mechanical strength, thermionic emission, and strong plasmonic properties. Recently, a new moderate-temperature synthetic technique was developed to directly synthesize LaB6 nanoparticles.

What is Lanthanum Hexaboride used for?
Lanthanum Boride gets wide applications, which successfully apply to radar system in aerospace, electronic industry, instrument, home appliance metallurgy, environmental protection and about twenty military and high tech industry.
LaB6 gets many uses in electron industry, which own better field emission property than tungsten(W) and other material. It is ideal material for high power electronic emission cathode.
It plays a role in highly stable and high life electron beam, for example electron beam engraving, electron beam heat source, electron beam welding gun. Monocrystal lanthanum boride is best cathode material for high power tube, magnetic control device, electron beam and accelerator.
Lanthanum Hexaboride nanoparticles are used as single crystal or as a coating on hot cathodes. Devices and techniques in which hexaboride cathodes are used include electron microscopes, microwave tubes, electron lithography, electron beam welding, X-ray tubes, and free electron lasers.
LaB6 is also used as a size/strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks.
LaB6 is a thermo electronic emitter and superconductor with a relatively low transition
