Magnesium diboride (MgB2) This is an ionic complex with a hexagonal crystalline structure. It is an intercalation-type compound, with alternate layers of magnesium or boron.
Researchers have found that the temperature at which magnesium boride transforms into a high-temperature superconductor is slightly below the absolute temperature of 233degC (40K). Its temperature of transition is about twice that of superconductors with the same type.

Many practical applications already exist for superconductivity such as magnetic levitation and medical imaging. Superconductors can be used in many other fields of technology, including medical imaging and magnetic levitation trains.

Magnesium diboride (MgB2) has been attracting the attention from researchers ever since it was discovered. It is a superconductor which offers many advantages. It is lightweight and easy to process, can be made out of many pre-materials. The total cost of using Magnesium Boride is greatly reduced.

Superconductors are characterized by their critical current densities (Jc). It is extremely difficult to increase MgB2’s Jc in an economical manner.

Researchers from Shibaura Institute of Technology, Japan, published an article in the journal “Materials Science and Engineering : B”. The paper describes how ultrasonic treatments can be used to improve mass. MgB2 JC.

Ultrasonic waves can be used to evenly disperse boron, which is a cheap commercial product. The hexane can then be vaporized and removed to obtain a fine powder, which will be sintered with the magnesium to create magnesium boride.

Researchers produce high-quality magnesium boride in bulk, the majority of which are free of oxidizing impurities. The Jc values increased 20% or more compared with the nonsonicated reference sample, depending on the time of sonication.
Moreover, scanning electron microscope and energy dispersive-X-ray spectrum results revealed a secondary mechanism that could lead to an enhancement of Jc. The team discovered a layered structure on the boron-deficient por walls. This appeared to consist of a magnesium boronoxide coating.

Researchers say that this will reduce the cost and technical difficulty of superconductors. It will also make it easier to use for the public, particularly in the medical sector.
