Lanthanum Hexaboride (LaB6) Ceramics

Lanthanum Hexaboride Description

lanthanum-hexaboride-productLanthanum Boride, also called Lanthanum Hexaboride or LaB6, is a refractory ceramic material. It has a high melting point of 2210 °C, and is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivity known, and is stable in vacuum. Therefore, the principal use of lanthanum hexaboride is a coating of hot LaB6 filament, or hot cathodes made of LaB6 crystals. 

Borides are hard, high-melting materials with metal-like conductivity, and they are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis. Borides are used in semiconductors, superconductors, diamagnetic, paramagnetic, ferromagnetic, anti-ferromagnetic, turbine blades, and rocket nozzles.

Advanced Ceramic Materials is a leading supplier of ceramic materials. We offer lanthanum boride products of high purity and with competitive prices.

Lanthanum Hexaboride Applications

The principal application of LaB6 is in hot cathodes, either as a single crystal or as a coating deposited by physical vapor deposition. LaB6 is a superconductor with a relatively low transition temperature of 0.45 K.

Other applications:

-Thermionic emission (cathode)
-Plasma source for plasma enhanced coating(PECVD)
-Vacuum electron beam welding machine
-Electron beam surface reforming device
-Electron beam lithography device
-Transmission electron microscope
-Scanning electron microscope
-Surface analysis device
-Radio therapy devices
