Lanthanum Hexaboride (LaB6):

Used as a high brightness thermionic emission materials because of its low work function, high melting point and high metallic conductivity, applied as Lanthanum Hexaboride (LaB6) cathode electron gun.

Application:
Vacuum electron beam welding machine
Electron beam surface reforming device
Electron beam lithography device
Transmission elctron microscope
Scanning elctron microscope
Surface analysis device
Radio therapy devices
Solar absorber and as electron source

We also produce LaB6 powder, LaB6 disc, LaB6 tablet, LaB6 target, LaB6 rod, LaB6 crucible, YB6 tube, Lab6 sector ring, CeB6, PrB6, NdB6, SmB6, EuB6, GdB6, TbB6, DyB6, HoB6, ErB6, TmB6, YbB6, LuB6, ScB6, (LaBa)B6, (LaEu)B6, CaB6, etc.
