BeschreibungTypical 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.
VerwendenCalcium 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).
synthetischeCalcium 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
