Where can calcium hexaboride be placed?
About calcium hexaboride CaB6 powder
It is an important material due to its high conductivity, hardness, chemical stability and melting point. It is black, shiny, and has the typical cubic structure of six metal borates, with an octahedral unit composed of six boron atoms and calcium atoms.
In the past, due to various special physical properties (such as superconductivity, valence fluctuations and Kondo effect), people have studied CaB6. However, the most significant characteristic of CaB6 is its ferromagnetism. It occurs at unexpectedly high temperatures (600K) and low magnetic moments. Nickel may come from impurities in the boron used to prepare the sample.
CaB6 does not compress H2O, MeOH (methanol) and EtOH (ethanol), and slowly dissolves acid. Its microhardness is 27 GPa, Knoop hardness is 2600 kg/mm2), Young's modulus is 379 GPa, and the resistivity of the pure crystal is greater than 2·1010Ω·m. CaB6 is a semiconductor with an estimated energy gap of 1.0 eV. The low semi-metal conductivity of many CaB6 samples can be explained by the accidental substitution of impurities and possible non-stoichiometry.
Product performance of calcium hexaboride CaB6 powder
Calcium hexaboride is black-gray powder or granules. The melting point is 2230℃, the relative density is 2.33g/cm, and it is insoluble in water at 15℃ and normal temperature. Calcium boride has the characteristics of a high melting point and high hardness. Its physical and chemical properties are quite stable. When calcined in air, sub-micron CaB6 will only increase in weight after 800 degrees Celsius and is not easily oxidized. CaB6 is generally insoluble in hydrochloric acid and sulfuric acid, so technically speaking, hot hydrochloric acid can be used to remove impurities, but CaB6 is soluble in nitric acid.
The main use of calcium boride
1. Used as a boron-containing additive for dolomite and magnesium dolomite refractories to resist oxidation, corrosion and improve thermal strength.
2. Used as a deoxidizing and degassing agent for high conductivity copper to improve conductivity and strength.
3. It is used as a new type of anti-neutron material in the nuclear industry.
4. Used as a new type of semiconductor material in spintronic components with a Curie temperature of 900K.
5. Used as a raw material for the manufacture of boron trichloride (BCl3) and amorphous boron.
6. Used as a raw material for manufacturing high-purity metal borides (TiB2, ZrB2, HfB2, etc.) and high-purity boron alloys (Ni-B, Co-B, Cu-B, etc.).
7. It is used to manufacture a mixture of calcium-boron nitride (Ca3B2N4) and hexagonal boron nitride containing catalyst, and use to produce crystalline cubic boron nitride with excellent performance.
8. Used as desulfurization, deoxidation and boron increase agent for boron alloy cast iron.
9. Used as desulfurization, deoxidation and boron increase agent for boron steel.
10. Used as a deoxidizer for metal smelting.
