Superconductivity of Magnesium Diboride MgB2 Powder

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.

Superconductivity of Magnesium Diboride MgB2 Powder

In 2001, researchers discovered that the seemingly inconspicuous magnesium boride becomes a superconductor at a temperature slightly closer to the absolute temperature of 40K (-233°C). Its transition temperature is almost twice that of other similar superconductors, and the actual operating temperature is 20-30K. The temperature can be cooled by liquid neon, liquid hydrogen or closed cycle freezers. These methods are simple and cost-effective compared to industrial cooling of niobium alloys (4K) using liquid helium.

Once doped with carbon or other impurities, magnesium boride is even better than niobium alloys at maintaining superconductivity in the presence of a magnetic field or electric current. Potential applications include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.

Magnesium Diboride MgB2 Powder Application

Potential applications for magnesium diboride include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.

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 oxidant 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.
