Chemical reagent. | [Description]
Magnesium diboride (MgB2) is a simple ionic binary
compound that has proven to be an inexpensive and
useful superconducting material. | [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. | [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. |
