What is Magnesium Boride MgB2 Powder?
The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.
Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the MgB2 powder may also be affected to a certain extent.
Introduction to Magnesium Boride MgB2 Powder
Magnesium diboride or magnesium boride, chemical formula MgB2, is an ionic compound with a hexagonal crystal structure.
It is an intercalated compound with alternating layers of magnesium and boron. The magnesium atomic layer has a triangular structure, and the boron atomic layer has a regular hexagonal honeycomb structure, which is similar to graphite.
Magnesium diboride is a hard and brittle substance with poor ductility.
Superconductivity of Magnesium Diboride MgB2 Powder
Researchers discovered in 2001 that the seemingly unremarkable magnesium boride turns into a superconductor at temperatures slightly closer to the absolute temperature of 40K (-233 ° C). Its transition temperature is almost twice that of other similar superconductors, and its actual operating temperature is 20 to 30K. The temperature can be cooled by liquid neon, liquid hydrogen, or a closed circulating freezer. These methods are simple and cost-effective compared to industrial cooling of niobium alloys (4K) with 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 current. Potential applications include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.

Applications of Magnesium Boride MgB2 Powder
Superconducting properties and low cost make magnesium diboride attractive in a variety of applications. For these applications, MgB2 powder is compressed into the wire with silver metal (or 316 stainless steel), sometimes through a powder in tube process to make tapes.
Thin coatings can be used in superconducting rf cavities to minimize energy loss and reduce the inefficiency of liquid helium cooling niobium cavities.
Due to the low cost of its components, MgB2 is expected to be used in superconducting medium and low field magnets, motors and generators, fault current limiters and current leads.
Propellants, explosives, fireworks:
Unlike the element boron, which burns incompletely through a glassy oxide layer that impedes oxygen diffusion, magnesium diboride burns completely when ignited in oxygen or in a mixture with an oxidant. Therefore, magnesium boride has been proposed as a ramjet fuel. In addition, the use of MgB2 in explosive-enhanced explosives and propellants has been proposed for the same reason. It was recently demonstrated that decoy flares containing magnesium diboride/PTFE/FLUORO rubber improved spectral efficiency by 30-60% compared to classic magnesium/Teflon/fluororubber (MTV) payloads. The application of magnesium diboride in rocket propulsion was also studied, where the compound was mixed in paraffin fuel particles to improve mechanical properties and combustion characteristics.
