What on earth is Calcium hexaboride?
Calcium hexaboride (often known as calcium boride) is a compound of calcium and boron. Its chemical method is CaB6. It's great electrical conductivity, superior hardness, chemical stability and superior melting position, and it is a grey-black reliable, glossy, inactive powder with very low density.
It has The everyday cubic construction of the metal boride, consisting of an octahedral unit of six boron atoms combined with calcium atoms. CaB6 and lanthanum-doped CaB6 equally show weak ferromagnetism, No.:12007-99-7, Microhardness is 27 GPa.Relative density two.33, Melting level 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 a semiconductor with an energy hole of about 1.0 electron volts. It truly is secure in air at superior temperatures, isn't going to respond with h2o, might be chlorine, fluorine, nitric acid, hydrogen peroxide, and also other robust oxidizing brokers, and reacts quite slowly and gradually with alkali.

Structural details: the crystal structure of CaB6 is really a cubic lattice, with calcium at the center from the cell and a three-dimensional boron network shaped by tightly normal octahedra of boron atoms related by boron bonds on the apex. Each calcium has 24 closest neighbor boron atoms. The calcium atoms are organized in an easy cubic stack so that cavities exist involving the eight calcium atoms Situated within the cube vertices. The easy cubic structure is extended via the introduction of octahedral B6 groups stuffed with calcium and hexaboride teams. An alternative strategy for describing calcium hexaboride is really a CsCl-form structure with metal B6 2-octahedral polymeric anions, While using the calcium atoms occupying
The NMR NMR info for 43Ca has a 未 peak at -fifty six.0 ppm along with a 未-iso at -41.three ppm, where by the maximum 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.eight, and 1246.nine cm-one because of activity modes A1g, Eg, and T2g, respectively.
Homes: The most outstanding house of CaB6 is its ferromagnetism. It appears unexpectedly at substantial temperatures (600 K) and very low magnetic times.
CaB6
Regular software products and solutions:
It is utilized as being a boron-containing additive for anti-oxidation, anti-erosion, and enhancing the power of sizzling state in dolomitic carbon and magnesian dolomitic carbon refractories. CaB6 can improve the toughness and bulk density of castables after procedure at all temperatures.
CaB6 can promote the diploma of substantial-temperature densification of castables so the castables can acquire much better oxidation resistance and better significant-temperature flexural power and erosion resistance. CaB6 can substantially improve the many Houses of iron hook castables. When including 0.five% calcium boride, the castables have superior thorough efficiency.
