Exactly what is Calcium hexaboride?
Calcium hexaboride (also referred to as calcium boride) is really a compound of calcium and boron. Its chemical system is CaB6. It has great electrical conductivity, large hardness, chemical security and high melting place, and is a gray-black reliable, shiny, inactive powder with low density.
It has The standard cubic framework of the metallic boride, consisting of the octahedral device of 6 boron atoms coupled with calcium atoms. CaB6 and lanthanum-doped CaB6 both exhibit weak ferromagnetism, No.:12007-99-seven, Microhardness is 27 GPa.Relative density two.33, Melting point 2200掳C, Knoop's hardness is 2600kg/mm2Young's modulus is 379GPaPure crystalline resistivity is greater than 2-ten ten惟-m.CaB6 is a semiconductor with the Strength gap of about 1.0 electron volts. It really is steady in air at substantial temperatures, won't respond with drinking water, might be chlorine, fluorine, nitric acid, hydrogen peroxide, and various potent oxidizing brokers, and reacts incredibly slowly but surely with alkali.
CaB6
Structural information and facts: the crystal composition of CaB6 is often a cubic lattice, with calcium at the middle in the cell and A 3-dimensional boron network fashioned by tightly frequent octahedra of boron atoms linked by boron bonds on the apex. Each and every calcium has 24 closest neighbor boron atoms. The calcium atoms are organized in a simple cubic stack so that cavities exist concerning the eight calcium atoms located for the cube vertices. The easy cubic construction is prolonged with the introduction of octahedral B6 teams stuffed with calcium and hexaboride teams. An alternate technique for describing calcium hexaboride can be a CsCl-kind composition with metal B6 2-octahedral polymeric anions, Using the calcium atoms occupying
The NMR NMR details for 43Ca includes a 未 peak at -fifty six.0 ppm along with a 未-iso at -forty one.three ppm, exactly where the utmost peak width of your 未-iso is taken for being 0.eighty five.
Raman data: Calcium boride has three Raman peaks at 754.3, 1121.8, and 1246.nine cm-one due to activity modes A1g, Eg, and T2g, respectively.
Houses: Essentially the most amazing property of CaB6 is its ferromagnetism. It appears unexpectedly at large temperatures (600 K) and very low magnetic times.
