About Magnesium Difboride MgB2 Poudre:
Magnesium boride is an inorganic compound. The molecular formula of magnesium diboride is also MgB2. Dark gray insoluble solid. It's an ionic with hexagonal crystal structure. It is an intercalated, alternating layer of magnesium and boran compound. This compound is of interest because it is superconducting at 39 K(-234degC).In terms of composition, MgB2 is markedly different from most transition-metal-based cryogenic superconductors.
Magnesium boride was known by scientists for more than 50 years. But no one ever tested its superconductivity, or whether it would conduct electricity flawlessly without resistance if cooled down to temperatures near absolute zero. It was only in 2001 that Jun Akimitsu, of Aoyama Gakuin University, Tokyo, announced that he had discovered that magnesium Diboride becomes superconducting below 39 degrees Kelvin. (-389 degrees Fahrenheit), which is nearly twice the temperature at which current intermetallic conducting materials become superconducting. It was a shock to the world when the announcement came out. Scientists from around the globe scrambled to confirm and duplicate the Japanese findings.
Magnesium diboride can be converted to a superconductor by a temperature just below 40K. (-233 deg. C). Its transition is almost twice as high as other superconductors. The actual operating temperature of this material is between 20-30K. You can reach this temperature by using liquid neon, hydrogen or a freezer with a closed circuit. These methods can be cheaper and easier than using liquid helium in the industry to cool niobium alloys (4K). After being doped with impurities such as carbon, magnesium boride maintains superconductivity just as well or even better as niobium when a magnetic current or field is present.

Magnesium is diboride, an ionic crystal compound with hexagonal structure. Magnesium diboride, at an absolute temperature of about 40K (equivalent -233), will transform into a high-temperature superconductor. The actual operating temperature of the superconductor is between 20 and 30K. For cooling, we can use liquid hydrogen, liquid neon or closed-cycle refrigeration to achieve this temperature. The methods used to cool the alloy are much simpler and cheaper than those currently being used by industry to cool niobium. If it's doped with impurities like carbon, then a magnetic field is applied, or if there is a passing current, the superconducting ability is equal to or better than niobium.

What is the production process of Magnesium Diaboride MgB2 Poudre ?
The MgB2 preparation is based on the reaction synthesis using a mixture of magnesium powder and boran powder.
MgB2 can be obtained by mixing 99.9% amorphous boron with 99% magnesium powder, at a ratio of 1:2. Then it is pressed into small balls before being heated in high-pressure Nitrogen.
Currently, the most commonly used method to synthesize magnesium boron is to mix amorphous boron and magnesium powder in a stoichiometric amount (or by adding excessive magnesium), put them together into a refractory container (such a tantalum), put them through a vacuum pump, and finally put them all inside a quartz tub for sintered at 700950°C for 14 hour.

Application of Magnesium MgB2 Diboride Powder ?
Magnesium-diboride superconductor, is the primary application. Magnesium diboride can be used in superconducting magnets and power transmission lines, as well as sensitive magnetic field detectors.
Magnesium diboride, a new material, is attracting attention. Research is mainly focused on synthesis of superconducting elements for industrial use, sintering, electrical conductivity and room temperature.
MgB2 and its composite materials are more readily sintered and densed than TiB2, allowing them to meet the electrical conductivity requirements for aluminum electrolysis. MgB2 as well as its composite materials will likely be widely used for cathodes in aluminum electrolysis.
Propellants, explosives, and pyrotechnics. Unlike boron which only burns partially through layers of glass oxide that block oxygen diffusion in mixtures with oxygen or oxidizers, magnesium diboride completely burns. It has therefore been suggested that magnesium boride could be used as fuel for the ramjet jet. MgB2 has also been suggested for use in explosives and propellants.

Conditions for storage of Magnesium Diboride (MgB2) powder

This product must be sealed, stored in an air-tight chamber that is cool and dry and kept away from the air to avoid moisture reunification. Moisture reunion will negatively affect the dispersion characteristics and the end result. It is important to avoid stress.
