Magnesium Diboride MgB2 Powder Specifications

Magnesium diboride MgB2 powder overview

Magnesium diboride is an inorganic compound with the molecular formula MgB2. It is a dark grey insoluble solid. It is an ionic compound with a hexagonal crystal structure. It is an intercalation compound with alternating layers of magnesium and boron. This compound is of interest because of its superconductivity at 39 K (-234°C). In terms of composition, MgB2 is significantly different from most transition metal-based low temperature superconductors.

How is magnesium diboride MgB2 powder produced?

The preparation method of MgB2 is mainly synthesized by the mixed reaction of magnesium powder and boron powder.

Mix 99.9% magnesium powder with 99% amorphous boron powder in a ratio of 1:2, press into small balls, and heat in high pressure nitrogen to obtain MgB2.

The current commonly used method is to mix amorphous elemental boron powder and magnesium powder in a stoichiometric ratio (or add excess magnesium), then put it into a sealed refractory metal container (such as tantalum), and then put it into a vacuum with a quartz tube , and then sintered at 700-950 ℃ for 1-4 h to synthesize MgB2.

Magnesium Diboride MgB2 Powder Application

Magnesium diboride is a new material that has attracted much attention. The research mainly focuses on the properties of synthesis and superconducting elements for industrial synthesis and sintering properties, room temperature electrical conductivity, corrosion resistance of liquid aluminum, corrosion resistance of fluoride resistance, etc. There are few studies, so MgB2 and its composite The material has cathode areas that are not used to cover the aluminum electrolysis.

MgB2 is easier to sinter and densify than TiB2, and its electrical conductivity basically meets the requirements of aluminum electrolysis cathodes. Therefore, MgB2 and its composites can be widely used as cathode materials for aluminum electrolysis.

Propellants, explosives, pyrotechnics: Unlike the incomplete combustion of elemental boron through a glass oxide layer that prevents the diffusion of oxygen, magnesium diboride burns completely in an oxygen or oxidizer mixture. Therefore, magnesium boride has been proposed as a fuel for ramjets. Also, for the same reason, it has been suggested to use MgB2 in enhanced explosives and propellants.
