Product Description Lanthanum hexaboride also called lanthanum boride (LaB6 ) is an inorganic non- metallic compound composed of low-valence boron and the rare metal element lanthanum. It is a refractory ceramic that could resist high temperature andharsh environments. Lanthanum hexaboride ceramic has lots of applications due to its ideal thermal, chemical, and electronic properties. As Lanthanum hexaboride has the characteristics of high emission current density and low evaporation rate at high temperature, it always work as a cathode material with superior performance and has gradually replaced some tungsten cathodes in industrial applications.
