Beschreibung
Typical samples of CaB6 are nonstoichiometric, i.e. the ratio of boron to calcium is not exactly 6:1, for example the ultra-fine powders of CaB6 produced by some researchers had B:Ca ratio of 5.91:1. It is an important material due to its high electrical conductivity, hardness, chemical stability, and melting point.Chemische Eigenschaften

Calcium boride is a black, lustrous, chemically inert powder with a low density. Calcium hexaboride is insoluble in H2O, MeOH (methanol), and EtOH (ethanol) and dissolves slowly in acids. It has the cubic structure typical for metal hexaborides, with octahedral units of six boron atoms combined with calcium atoms.Verwenden
Calcium boride is used as an electrode (cathode) material and n-type thermoelectric materials. It is used to make boron- alloyed steel, as a deoxidation agent in the production of oxygen-free copper. It is further used as an antioxidant in carbon bonded refractories. It acts as a new material which is used in the nuclear-industry for neutron- preventing, high-purity metal borid (TiB2,ZrB2,HfB2) and high-purity boron alloy(Ni-B, Co-B, Cu-b).synthetische
Calcium boride can be formed directly from the elements. Ca melts at 842°C and boron melts at 2076°C. Therefore, if a vapor of Ca metal at >850°C (red-heat) is passed over crystals of boron, a gas–solid reaction forms the desired boride. However, to obtain stoichiometric compositions, it is better to heat the well-mixed powders of Ca and B to obtain specific compounds:Ca+ 6B→CaB6
