Lanthanum Hexaboride Sheet/Plate is used as cathode and even crucibles for the electric industry and frontier research. SAM provides lanthanum boride Plates and other LaB machined parts for both prototyping and scaled up productions: Lanthanum boride sputter target, Lanthanum boride (LaB) Slab/Tablet
As the Lanthanum: boron ratio is less than 1:4, LaB6 is considered a boron-rich material. Compared with other boride ceramics, lanthanum boride sheet, LaB6 sheet/plate, has more applications. This material could be machined into simple shapes, to be used as cathode and even crucibles for the electric industry and frontier research.
