As a leading global supplier of advanced ceramics, Stanford Materials Corporation (SMC) provides consistently high-quality Lanthanum Hexaboride Rods (LaB6 ceramic rods). We're capable of supplying custom materials per any specs/drawings you provide us with.
Lanthanum Hexaboride Rod (LaB6 Rod) is an inorganic chemical. With a melting point of 2528 K, LaB6 is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in a vacuum. Stoichiometric samples are colored intensely 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.
