What is Calcium hexaboride?

Calcium hexaboride (sometimes calcium boride) is a compound of calcium and boron with the chemical formula CaB6. It is an essential 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. This is 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 due to various 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.

 

CaB6 is a semiconductor with an energy gap estimated at 1.0 eV.

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 CaB6 is insoluble in H2O, MeOH (methanol), and EtOH (ethanol) and dissolves slowly in acids. The contaminants might include iron and nickel, probably coming from impurities in the boron used to prepare the sample. This high-temperature ferromagnetism originates from the ferromagnetic phase of the dilute electron gas, linkage to the presumed excitonic state in calcium boride, or external impurities on the sample's surface.

 

What is the synergy of calcium and boron?

Calcium and boron have low mobility in the plant. The plant's mobility of these two elements is affected by water absorption, evaporation, and transpiration. Studies show that combined consumption of calcium and boron increases calcium mobility and accumulation in leaves and fruits. Calcium is a mineral responsible for making bones strong. Boron could help enhance bone health by increasing how long vitamin D works in your body. According to an article in The Open Orthopaedics Journal, people with low vitamin D levels are more likely to have low levels of boron. Calcium can react violently with WATER, STEAM, MOISTURE, and STRONG ACIDS (such as HYDROCHLORIC, SULFURIC, and NITRIC) to form flammable and explosive Hydrogen gas.
