Lanthanum hexaboride ceramic

WebbLanthanum Hexaboride Tube (LaB6 tube) is an inorganic chemical. With a melting point of 2528 K, the LaB6 tube is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in a vacuum. Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6 tube) are blue. WebbLanthanum Hexaboride (LaB6, also called lanthanum boride) is an organic chemical, a boride of Lanthanum. It is a refractory metal material that had a melting point of 2210°C and is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivities known and is stable in a vacuum.
