| MAGNESIUM BORIDE Usage And Synthesis |
| Description | Magnesium diboride (MgB2) is a simple ionic binary
compound that has proven to be an inexpensive and
useful superconducting material. | | Chemical Properties | hexagonal crystal(s); -100mesh with 99% purity; refractory material [CER91] [KIR78] [LID94] | | Chemical Properties | Magnesium Boride is brown solid, by reaction of boron oxide and magnesium powder ignited. | | Physical properties | Its molecular weight is 45.9325 g/mol. Magnesium Boride melts at 830°C
and is hexagonal with space group P6/mmm and lattice
constants of a=3.0864? , c=3.5215 ?. The density is
2.625 g/cm3 and the hardness is 1260 kg/mm2. | | Uses | Chemical reagent. | | Uses | Magnesium Boride exhibits super conducting properties and utilized in MRI superconducting magnet, which is a closed-loop cryocooler. It is used as propellants, pyrotechnics and explosives. It can be used as high temperature boron-based thermoelectric materials. It is also used in superconducting transformers, rotors, transmission cables, superconducting radio frequency cavities to minimize energy loss. | | Preparation | Magnesium boride can be formed directly from the
elements. Mg melts at 650 °C and boron melts at
2076 °C. Therefore, if a vapor of Mg metal at >750°C
(red-heat) is passed over crystals of boron, reaction
forms the desired boride. However, to obtain a stoichiometric
compositions, it is better to heat the well-mixed
powders of Mg and B to obtain specific compounds:
Mg + 2B→MgB2 | | General Description | Magnesium boride (MgB2) powder is a superconductive material which has a critical temperature (Tc) = 39K. It can be used for a variety of applications such as hydrogen storage, high energy fuel and high field superconductors. |
