· Ho1 B6

Ho1B6 is a rare-earth hexaboride ceramic compound combining holmium with boron in a 1:6 stoichiometry, belonging to the family of lanthanide hexaborides studied for their exceptional electron emission and refractory properties. This material is primarily investigated in research contexts for thermionic cathodes, high-temperature electron sources, and specialized vacuum electronics applications where its low work function and thermal stability offer advantages over conventional tungsten or lanthanum hexaboride alternatives.
