Stanford Advanced Materials supplies our customers with high quality Lanthanum Hexaboride ceramic part (LaB6 ceramic). Other shape of LaB6 ceramic product: Lanthanum boride sputter target, Lanthanum Hexaboride (LaB6) Powder
Lanthanum Hexaboride (LaB6, also called lanthanum boride and LaB6) is an inorganic chemical. With melting point 2528 K, LaB6 is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in vacuum. Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6.07) are blue. Ion bombardment changes its color from purple to emerald green. LaB6 is a superconductor with a relatively low transition temperature of 0.45 K.
