Lanthanhexaboride (LaB6) Parts Description
Lanthanhexaboride (LaB6, also known as Lanthanboride and LaB6) is an inorganic chemical. With a melting point of 2 528 K, LaB6 is a refractory ceramic material that is insoluble in water or hydrochloric acid and remains very stable in a vacuum. Stoichiometric samples display an intense purple-violet colour, whereas boron-rich samples (exceeding LaB6.07) appear blue. Ion bombardment changes the colour from violet to emerald green. LaB6 is a superconductor with a relatively low transition temperature of 0.45 K.
