What on earth is Calcium hexaboride?
Calcium hexaboride (also known as calcium boride) is really a compound of calcium and boron. Its chemical formula is CaB6. It's got great electrical conductivity, substantial hardness, chemical balance and high melting issue, which is a gray-black stable, glossy, inactive powder with small density.
It's The everyday cubic framework of the steel boride, consisting of the octahedral unit of 6 boron atoms combined with calcium atoms. CaB6 and lanthanum-doped CaB6 both equally exhibit weak ferromagnetism, No.:12007-99-seven, Microhardness is 27 GPa.Relative density 2.33, Melting place 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 often a semiconductor with the energy gap of about one.0 electron volts. It is steady in air at superior temperatures, isn't going to 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 construction of CaB6 is a cubic lattice, with calcium at the middle from the mobile and a three-dimensional boron network fashioned by tightly standard octahedra of boron atoms connected by boron bonds for the apex. Each and every calcium has 24 closest neighbor boron atoms. The calcium atoms are arranged in a straightforward cubic stack to ensure cavities exist concerning the eight calcium atoms Positioned in the dice vertices. The easy cubic construction is prolonged from the introduction of octahedral B6 groups crammed with calcium and hexaboride groups. An alternative method of describing calcium hexaboride can be a CsCl-variety framework with steel B6 2-octahedral polymeric anions, With all the calcium atoms occupying
The NMR NMR data for 43Ca incorporates a 未 peak at -56.0 ppm and a 未-iso at -forty one.three ppm, exactly where the utmost peak width of your 未-iso is taken to become 0.85.
Raman knowledge: Calcium boride has a few Raman peaks at 754.three, 1121.eight, and 1246.9 cm-one on account of exercise modes A1g, Eg, and T2g, respectively.
Attributes: The most exceptional house of CaB6 is its ferromagnetism. It appears unexpectedly at substantial temperatures (600 K) and small magnetic times.
