Lanthanhexaboride (LaB6) Ring Description
Lanthanhexaboride (LaB6), also known as Lanthanboride, is an inorganic chemical. With a melting point of 2528 K, the LaB6 Ring is a refractory ceramic material that is insoluble in water or hydrochloric acid and remains very stable in vacuum. Stoichiometric samples exhibit an intense violet colour, whereas boron‐rich samples (exceeding LaB6.07) appear blue. Ion bombardment changes the colour from violet to emerald green. LaB6 functions as a superconductor with a transition temperature of 0.45 K.
