What exactly is Calcium hexaboride?
Calcium hexaboride (also known as calcium boride) is often a compound of calcium and boron. Its chemical formula is CaB6. It has outstanding electrical conductivity, significant hardness, chemical security and significant melting point, and is a gray-black solid, shiny, inactive powder with low density.



It's got The everyday cubic framework of a metal boride, consisting of an octahedral device of 6 boron atoms combined with calcium atoms. CaB6 and lanthanum-doped CaB6 the two exhibit weak ferromagnetism, No.:12007-ninety nine-seven, Microhardness is 27 GPa.Relative density 2.33, Melting stage 2200掳C, Knoop's hardness is 2600kg/mm2Young's modulus is 379GPaPure crystalline resistivity is greater than two-ten 10惟-m.CaB6 is really a semiconductor with an Power hole of about one.0 electron volts. It really is stable in air at high temperatures, would not respond with water, can be chlorine, fluorine, nitric acid, hydrogen peroxide, and other potent oxidizing agents, and reacts extremely slowly with alkali.

CaB6

Structural information and facts: the crystal framework of CaB6 is actually a cubic lattice, with calcium at the middle on the cell and a three-dimensional boron community shaped by tightly regular octahedra of boron atoms linked by boron bonds in the apex. Each individual calcium has 24 nearest neighbor boron atoms. The calcium atoms are organized in a simple cubic stack making sure that cavities exist among the 8 calcium atoms located for the cube vertices. The straightforward cubic composition is extended because of the introduction of octahedral B6 groups full of calcium and hexaboride teams. Another means of describing calcium hexaboride is usually a CsCl-sort composition with metallic B6 2-octahedral polymeric anions, Along with the calcium atoms occupying

The NMR NMR information for 43Ca is made up of a 未 peak at -fifty six.0 ppm along with a 未-iso at -41.3 ppm, wherever the most peak width from the 未-iso is taken to get 0.eighty five.

Raman details: Calcium boride has three Raman peaks at 754.3, 1121.8, and 1246.9 cm-1 as a result of action modes A1g, Eg, and T2g, respectively.


Houses: Probably the most impressive residence of CaB6 is its ferromagnetism. It seems unexpectedly at significant temperatures (600 K) and small magnetic times.

Usual software products:

It's utilized like a boron-that contains additive for anti-oxidation, anti-erosion, and bettering the power of sizzling state in dolomitic carbon and magnesian dolomitic carbon refractories. CaB6 can improve the strength and bulk density of castables after treatment at all temperatures.

CaB6 3d printed can promote the diploma of substantial-temperature densification of castables so the castables can get much better oxidation resistance and better significant-temperature flexural energy and erosion resistance. CaB6 can drastically improve the many Houses of iron hook castables. When incorporating 0.5% calcium boride, the castables have improved thorough functionality.
