Lanthanum hexaboride (LaB6) is one of the most advanced thermionic emission materials, primarily due to its low work function and high melting point. Denka LaB6 Cathode products have achieved a valued reputation in the marketplace as the leading electron source for electron microscopes and electron beam lithography apparatus.
Denka’s LaB6 Cathodes feature a single crystal of high purity and high quality LaB6 grown by floating zone techniques, which imparts reliable and stable emission characteristics. Sophisticated machining covers various cone angles and dimensions. Denka is also the only manufacturer capable of providing highly advanced hemispherical-shaped tips.
