Scope

This standard specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of lanthanum hexaboride.
This standard applies to lanthanum hexaboride powders obtained by reducing lanthanum oxide with boron carbide (or pure boron), polycrystalline lanthanum hexaboride prepared by hot pressing, and monocrystalline lanthanum hexaboride produced by arc method. This product is mainly used as a cathode emission material.
