Calcium Boride Powder Description:

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 which are a remarkable fact because calcium and boron are neither magnetic nor have inner 3d or 4f electronic shells, which are usually required for ferromagnetism.

It has been investigated in the past due to a variety of peculiar physical properties, such as superconductivity, valence fluctuation, and Kondo effects.

However, the most remarkable property of CaB is its ferromagnetism. It occurs at unexpectedly high temperatures and with a low magnetic moment.

The origin of this high-temperature ferromagnetism is the ferromagnetic phase of the dilute electron gas, linkage to the presumed excitonic state in calcium boride, or external impurities on the surface of the sample.

The impurities might include iron and nickel, probably coming from impurities in the boron used to prepare the sample.

CaB6 is insoluble in H2O, MeOH (methanol), and EtOH (ethanol) and dissolves slowly in acids.

Its microhardness is 27 GPa, Knoop hardness is 2600 kg/mm2), the Young modulus is 379 GPa, and electrical resistivity is greater than 2·1010 Ω·m for pure crystals.

CaB6 is a semiconductor with an energy gap estimated at 1.0 eV. The low, semi-metallic conductivity of many CaB6 samples can be explained by unintentional doping due to impurities and possible non-stoichiometry
