What is Magnesium Boride MgB2 Powder?

Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.  

Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine.  Even before the war, the aluminium market was suffering from long waiting times and weak demand.  

For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases.  Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020.  This was mainly due to a slowdown in new orders and MgB2 powder are expected to increase in the future.

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
Superconductors:
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.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.  

On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.  

Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.  

Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March.  It is also the highest since comparable data began in 1999.  

The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the MgB2 powder.
