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 as high compared to other superconductors.

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 a magnet for researchers ever since it was discovered. It is a superconductor which offers many advantages. Magnesium Boride is an easy-to-process, lightweight material that can be produced from many different pre-materials. Its low cost allows it to be used in many applications.

Superconductors are characterized by their critical current densities (Jc). However, it’s very difficult to increase MgB2’s Jc in an economical manner.

In a recent paper published in Materials Science and Engineering (B) (Materials Science and Engineering), researchers from Shibaura Institute of Technology, Japan have developed a new technology that uses ultrasound treatment to improve mass. MgB2 JC.

The method used is to use ultrasonic wave to completely disperse boron. The hexane can then be vaporized and removed to obtain a fine boron, which will then 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. Jc values increased 20% or more compared with the nonsonicated reference sample, depending on sonication duration.
In addition, 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.
