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 fantastic electrical conductivity, higher hardness, chemical balance and large melting position, which is a grey-black reliable, glossy, inactive powder with lower density.
It's the typical cubic structure of the metallic boride, consisting of the octahedral unit of six boron atoms coupled with calcium atoms. CaB6 and lanthanum-doped CaB6 both of those show weak ferromagnetism, No.:12007-99-7, Microhardness is 27 GPa.Relative density two.33, Melting issue 2200掳C, Knoop's hardness is 2600kg/mm2Young's modulus is 379GPaPure crystalline resistivity is bigger than 2-10 ten惟-m.CaB6 is often a semiconductor by having an Electricity gap of about 1.0 electron volts. It is actually steady in air at substantial temperatures, will not react with h2o, might be chlorine, fluorine, nitric acid, hydrogen peroxide, and also other robust oxidizing agents, and reacts incredibly bit by bit with alkali.
CaB6
Structural data: the crystal structure of CaB6 is usually a cubic lattice, with calcium at the center from the mobile and a three-dimensional boron network formed by tightly common octahedra of boron atoms connected by boron bonds for the apex. Every single calcium has 24 closest neighbor boron atoms. The calcium atoms are arranged in a straightforward cubic stack in order that cavities exist between the eight calcium atoms Found on the dice vertices. The simple cubic framework is prolonged through the introduction of octahedral B6 teams filled with calcium and hexaboride groups. Another strategy for describing calcium hexaboride is actually a CsCl-style construction with steel B6 two-octahedral polymeric anions, Using the calcium atoms occupying
The NMR NMR facts for 43Ca contains a 未 peak at -56.0 ppm and also a 未-iso at -forty one.three ppm, exactly where the utmost peak width with the 未-iso is taken to be 0.85.
Raman info: Calcium boride has 3 Raman peaks at 754.three, 1121.eight, and 1246.nine cm-one as a consequence of activity modes A1g, Eg, and T2g, respectively.
Qualities: Quite possibly the most remarkable home of CaB6 is its ferromagnetism. It appears unexpectedly at large temperatures (600 K) and very low magnetic times.
