Lanthanum hexaboride (LaB6, also called lanthanum boride and LaB) is an inorganic chemical, a boride of lanthanum. It is a refractory ceramic material that has 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 vacuum. Lanthanum Hexaboride is highly insoluble in water and converts to the oxide when heated (calcined).

Material Notes

Lanthanum Hexaboride Sputtering Target, Purity is 99.5%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. Bonding is recommended for these materials. Many materials have characteristics which are not amenable to sputtering, such as, brittleness and low thermal conductivity.This material may require special ramp up and ramp down procedures. This process may not be necessary with other materials. Targets that have a low thermal conductivity are susceptible to thermal shock.
