What on earth is Calcium hexaboride?
Calcium hexaboride (also referred to as calcium boride) is a compound of calcium and boron. Its chemical system is CaB6. It has exceptional electrical conductivity, high hardness, chemical balance and higher melting point, which is a gray-black solid, shiny, inactive powder with reduced density.



It's got The standard cubic structure of the metal boride, consisting of an octahedral device of six boron atoms coupled 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 issue 2200掳C, Knoop's hardness is 2600kg/mm2Young's modulus is 379GPaPure crystalline resistivity is larger than two-10 ten惟-m.CaB6 is really a semiconductor by having an Strength hole of about 1.0 electron volts. It can be stable in air at significant temperatures, doesn't respond with water, might be chlorine, fluorine, nitric acid, hydrogen peroxide, as well as other solid oxidizing brokers, and reacts really slowly but surely with alkali.

CaB6

Structural data: the crystal composition of CaB6 is really a cubic lattice, with calcium at the center of your cell and a three-dimensional boron network shaped by tightly frequent octahedra of boron atoms connected by boron bonds with the apex. Each individual calcium has 24 nearest neighbor boron atoms. The calcium atoms are arranged in an easy cubic stack making sure that cavities exist between the eight calcium atoms Situated with the dice vertices. The easy cubic composition is prolonged from the introduction of octahedral B6 groups full of calcium and hexaboride groups. An alternate means of describing calcium hexaboride is often a CsCl-style structure with metal B6 two-octahedral polymeric anions, With all the calcium atoms occupying

The NMR NMR knowledge for 43Ca has a 未 peak at -fifty six.0 ppm and also a 未-iso at -forty one.3 ppm, the place the utmost peak width on the 未-iso is taken to get 0.85.

Raman info: Calcium boride has 3 Raman peaks at 754.3, 1121.eight, and 1246.nine cm-one on account of action modes A1g, Eg, and T2g, respectively.


Qualities: One of the most impressive house of CaB6 is its ferromagnetism. It appears unexpectedly at higher temperatures (600 K) and reduced magnetic times.

CaB6

Regular application items:

It's utilized as a boron-made up of additive for anti-oxidation, anti-erosion, and strengthening the power of scorching point out in dolomitic carbon and magnesian dolomitic carbon refractories. CaB6 can Enhance the strength and bulk density of castables after cure in any way temperatures.

CaB6 can advertise the diploma of substantial-temperature densification of castables so that the castables can attain greater oxidation resistance and higher significant-temperature flexural power and erosion resistance.
