Magnesium diboride is an ionic compound, with hexagonal crystal structure. Magnesium diboride at absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen or closed-cycle refrigerator to finish cooling. Compared to current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.  

Application: 
superconducting magnets, power transmission lines and sensitive magnetic field detectors. 


Storage Conditions:

This product should be sealed and stored in a cool, drying chamber and should avoid exposing to the air in order to prevent moisture reunion which will affect the dispersion properties and result use. Stress should be avoided.
