Calcium Boride

Calcium and Boron is a chemical compound.

Calcium Boride Chemical Formula

CaB6 is an important material. CaB6 is a material of importance due to its high conductivity.

Calcium boride powder

This is a dense, black, glossy powder. It has a typical cube structure with six metal borides, octahedral boron and calcium atoms.


It has been studied in the past because of its unique physical properties. These include superconductivity. CaB6 has a remarkable ferromagnetism. This occurs unexpectedly at high temperatures (600K) with a low magnetization moment. This high temperature ferromagnetism may be caused by the ferromagnetic phases of dilute electron gases, a linkage to a presumed excitonic condition in calcium boreide, or impurities externally on the surface. Iron and nickel impurities are possible, which probably come from the impurities of the boron used in preparing the sample.


Calcium Boride

Insoluble in water, MeOH (methanol), EtOH (ethanol), and Slowly dissolves in acid. It has a microhardness (27 GPa), Knoop hardness (2600 kg/mm2), Young modulus (379 GPa) and an electrical resistivity greater than 2*1010 O*m.

CaB6 is an electronic semiconductor

With an estimated energy gap of 1.0 eV. Many CaB6 sample’s low semi-metallic resistance can be explained by the unintentional contamination of impurities, and possibly non-stoichiometry.

Product Performance of CaB6 Calcium Hexaboride Powder

It is also characterized by high melting points and hardness. Physically and chemically, it is stable. CaB6 sub-microns are not easily oxidized when they are calcined. CaB6 does not dissolve in hydrochloric or sulfuric acids. Nitric acid is the only way to remove impurities.

Calcium Hexaboride CaB6 Powder


One of the major reactions of industrial production:

CaO + B2O3 + 10 mg-CaB6 + MgO

CaB6 powder can be made in a variety of ways.

The reaction between calcium or calcium oxidide and boron occurs at 1000degC.

Ca + 6B-CaB6

Under vacuum, the reaction of Ca(OH),2 with boron is 1700degC.

Ca(OH)2 + 7B-CaB6 + BO(g)+ H2O(g)

The reaction between boron carbide and calcium carbonate under vacuum is above 1400degC.

CaO and h3BO3 react when Mg reaches 1100degC.

Low temperature (500degC ) Synthesis

CaCl2 + 6NaBH4-CaB6 + 2NaCl + 12H2 + 4Na

In the end, material quality was poor.

The CaB6 is then recrystallized by zone melting to obtain pure CaB6 crystals for cathode materials. The growth rate is typically 30 cm/h and the size of the crystals is 1×10 cm.

In the presence of Ni catalyst, single crystal CaB6 Nanowires can be made by pyrolyzing Diborane (B2H6) onto calcium oxide (CaO).
