About Magnesium Difboride MgB2 Poudre:
Magnesium boride is an inorganic substance. The molecular formula of magnesium diboride is MgB2. Dark gray insoluble solid. It's an ionic with hexagonal crystals. 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 his research team found that magnesium Diboride becomes superconducting as low as 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 world were scrambling for ways to duplicate and confirm the Japanese results.
Magnesium diboride can be converted to a superconductor by bringing it up to temperatures slightly below 40K. (-233 deg. C). Its transition is almost twice as high compared to 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). Once doped by carbon or other impurities magnesium Boride can maintain superconductivity as well as or better than niobium in the presence a magnetic or current field.

Magnesium is a 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 a closed-cycle refrigerator. The methods used to cool niobium alloys (4K) are much simpler and cheaper than those currently being used by the industry. If it is doped in with carbon or impurities or magnesium diboride and a magnetic field is applied, or a current is passed, then the ability to maintain superconductivity is the same as or better than niobium.

What is the production process of Magnesium Diaboride MgB2 Poudre ?
The MgB2 preparation is primarily a reaction synthesis using magnesium powder and mixed boron.
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 in an airtight refractory container (such a tantalum), vacuum pump the mixture, and then place it into a quartz tube.

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.
The new material of magnesium diboride, the focus of research is on the synthesis of superconducting materials for industrial use, electrical conductivity in room temperature. Studies of the corrosive resistance and liquid aluminum corrosion resistance of fluoride are less.
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 cathode materials 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 in ramjets. MgB2 has also been suggested for use in explosives and propellants.
