MAGNESIUM BORIDE Chemical Properties,Uses,Production
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.
