Tlhaloso e Khutšoanyane:

Lanthanum Hexaboride (LaB6,e boetse e bitsoa lanthanum boride le LaB) ke lik'hemik'hale tse sa tloaelehang, boride ea lanthanum. Joalo ka thepa ea ceramic e refractory e nang le ntlha ea ho qhibiliha ea 2210 ° C, Lanthanum Boride ha e qhibilihe haholo metsing le hydrochloric acid, 'me e fetohela ho oxide ha e chesa (calcined). Mehlala ea Stoichiometric e na le 'mala o pherese-violet o matla, ha tse nang le boron (ka holimo ho LaB6.07) li le putsoa.Lanthanum Hexaboride(LaB6) e tsejoa ka ho thatafala ha eona, matla a mochine, tlhahiso ea thermionic, le thepa e matla ea plasmonic.
