Called calcium hexaboride or calcium boride sometimes, it is a combination of calcium and bore with the chemical composition CaB6. This material is important due to its high electric conductivity, hardness and chemical stability.
Calcium Hexaboride CaB6 Pulver:
Calcium Hexaboride, Calcium Boride is an alloy of calcium and bore. Calcium boride’s chemical formulais CaB6. This material is important due to its high conductivity and hardness as well as chemical stability, melting point, and chemical stability. The calcium boride powder, a dark, shiny and chemically inert, is low in density. This cubic structure contains six metal Boride atoms, and six boron atoms.
CaB6 is a unique physical property that has been studied in the past. These include superconductivity (valence fluctuation) and Kondo effects. CaB6’s most notable property is its ferromagnetism. The unexpectedly high temperature (600K), and low magnetic moment are the reasons it occurs. High-temperature ferromagnetism results from the formation of the ferromagnetic phase in dilute electron gas. This linkage is to the presumed exitonic state found in calcium boride. These impurities could include nickel and iron, likely due to impurities present in the boron which was used to prepare it.
sodium boride is not soluble in water, MeOH and EtOH and slowly dissolves in acids. It has a microhardness value of 27 GPa and a Knoop hardness of 2600 kg/mm2. The Young modulus for pure crystals is 379 GPa. Electrical resistivity is higher than 21010 m. caB6 is a semiconductor that has an energy gap of approximately 1.0 electronvolts. Many CaB6 sample’s low conductivity can be explained with unintentional Doping.

Product Performance of Calcium Hexaboride CaB6 Powder:
Calcium Boride is known for its high melting point, high hardness and other characteristics. Both its chemical and physical properties are stable. The sub-micron CaB6 does not gain much weight when calcined under air conditions. It is also difficult to oxidize. CaB6 cannot be removed from hot hydrochloric or sulfuric acid. Technically, however, CaB6 may still dissolve in nitric and hydrochloric.
How iscalcium hexaboride caB6 powder?
The main reaction of industrial production is:
CaO + 3 B2O3 + 10 Mg→CaB6 + 10 MgO
CaB6 Powder can be produced in many other ways, including:
At 1000°C, calcium and/or calcium oxide will react directly with boron
Ca + 6B→CaB6
In a vacuum at about 1700°C (carbothermal reduce), Ca(OH)2 reacts positively with Boron.
Ca(OH)2 + 7B→CaB6 + BO(g)+ H2O(g)
Reaction of calcium carbonate with boron caride in vacuum over 1400°C (Carbothermal reduce)
CaO, H3BO3, and Mg react to each other up to 1100°C
Low temperatures (500°C), synthesis
CaCl2 + 6NaBH4→CaB6 + 2NaCl + 12H2 + 4Na
This has led to a low quality material.
CaB6 powder can be further reconstituted and purified using zone melting technology to make single crystals. It is possible to grow at a rate of about 30 cm/h and have crystal sizes around 1×10 cm.
By pyrolyzing diborane powder on calcium oxide (CaO), the temperature can reach 860-900°C and isaccompanied by Ni catalyst, single crystal CaB6 3pdm wires are possible (diameter between 15-40 nm, height 1-10 microns).
Technical Parameters of Calcium Hexaboride Powder CaB6:
Calcium Hexaboride Powder CaB6:
1. It is used as an additive containing boron for magnesium dolomite coal refractories, to resist oxidation and erosion and increase the thermal strength.
2. This is used as a deoxidizing or degassing agent to enhance conductivity and strength of highly conductive red-colored copper.
3. This material is used as an innovative type of material to stop neutrons being released into the nuclear industry.
4. This material is used as a semiconductor material for new spin electronic components at temperatures of 900K.
5. This is used to produce boron trichloride (BCl3) as well as amorphousboron.
6. This is used to produce high-purity metal borids (TiB2, ZrB2, FfB2, etc.). and high-purity, boron alloys, such as Ni-B (Co-B), Cu-B (etc.). ).
7. It is used for the manufacture of a mix of catalyst-containing calcium boron (Ca3B2N4) & hexagonal Boron nitride (Ca3B2N4). Also, to create crystal cubic and high-performance boron.
Calcium Hexaboride CaB6 Pulp:
CaB6 powder performance and usage effects can be affected by damp reunion. CaB6 Powder should therefore be stored in vacuum packaging and in a cool dry place. CaB6 powder should not be exposed to stress.
