What is Calcium hexaboride?
Calcium hexaboride (generally known as calcium boride) is actually a compound of calcium and boron. Its chemical system is CaB6. It's got exceptional electrical conductivity, large hardness, chemical stability and superior melting place, and is also a gray-black strong, glossy, inactive powder with low density.



It's got The everyday cubic composition of the steel boride, consisting of an octahedral device of 6 boron atoms combined with calcium atoms. CaB6 and lanthanum-doped CaB6 equally exhibit weak ferromagnetism, No.:12007-99-seven, Microhardness is 27 GPa.Relative density 2.33, Melting level 2200掳C, Knoop's hardness is 2600kg/mm2Young's modulus is 379GPaPure crystalline resistivity is greater than 2-ten ten惟-m.CaB6 can be a semiconductor with an Electrical power gap of about 1.0 electron volts. It is steady in air at superior temperatures, will not respond with water, could be chlorine, fluorine, nitric acid, hydrogen peroxide, and other solid oxidizing agents, and reacts very slowly but surely with alkali.

CaB6

Structural facts: the crystal construction of CaB6 is often a cubic lattice, with calcium at the center of the mobile and a three-dimensional boron network shaped by tightly normal octahedra of boron atoms linked by boron bonds in the apex. Each calcium has 24 nearest neighbor boron atoms. The calcium atoms are organized in a simple cubic stack to make sure that cavities exist in between the eight calcium atoms Situated on the cube vertices. The straightforward cubic framework is extended because of the introduction of octahedral B6 teams stuffed with calcium and hexaboride teams. An alternate strategy for describing calcium hexaboride is usually a CsCl-style composition with metallic B6 two-octahedral polymeric anions, with the calcium atoms occupying

The NMR NMR data for 43Ca consists of a 未 peak at -fifty six.0 ppm and a 未-iso at -forty one.three ppm, the place the utmost peak width in the 未-iso is taken for being 0.85.

Raman data: Calcium boride has a few Raman peaks at 754.three, 1121.8, and 1246.nine cm-1 on account of activity modes A1g, Eg, and T2g, respectively.


Properties: One of the most exceptional home of CaB6 is its ferromagnetism. It seems unexpectedly at significant temperatures (600 K) and lower magnetic moments.

CaB6

Typical software items:

It's used for a boron-that contains additive for anti-oxidation, anti-erosion, and enhancing the toughness of very hot state in dolomitic carbon and magnesian dolomitic carbon refractories. CaB6 can Enhance the strength and bulk density of castables just after treatment method whatsoever temperatures.

CaB6 can endorse the degree of superior-temperature densification of castables so that the castables can attain far better oxidation resistance and better large-temperature flexural toughness and erosion resistance. CaB6 can substantially Increase the numerous Houses of iron hook castables. When adding 0.5% calcium boride, how to 3d print the castables have improved extensive general performance.
