Calcium hexaboride (sometimes calcium boride) is a compound of calcium and boron with the chemical formula CaB6. It is an important material due to its high electrical conductivity hardness chemical stability and melting point. It is a black lustrous chemically inert powder with a low density. It has the cubic structure typical for metal hexaborides with octahedral units of 6 boron atoms combined with calcium atoms.
