Lanthanum Hexaboride (LaB6,kapa ʻia hoʻi ka lanthanum boride a me LaB) he mea ʻano kemika, he boride o ka lanthanum. E like me refractory ceramic mea i loaʻa kahi heheʻe o 2210 °C, Lanthanum Boride mea loa insoluble i ka wai a me ka hydrochloric waika, a hoohuli i ka oxide ke wela (calcined). ʻO nā laʻana Stoichiometric i waihoʻoluʻu i ka poni-violet, aʻo nā mea waiwai boron (ma luna o LaB6.07) he uliuli.Lanthanum Hexaboride(LaB6) ʻike ʻia no kona paʻakikī, ikaika mechanical, thermionic emission, a me nā waiwai plasmonic ikaika. I kēia mau lā, ua hoʻomohala ʻia kahi ʻenehana synthetic hou no ka hoʻopili pololei ʻana i nā nanoparticles LaB6.
