Efficient Method of Creating Metallic Plasmas from Solid Metals under a Strong Magnetic Field
Hot gases composed of metal ions and electrons, known as plasmas, are widely used in many manufacturing processes and chemical synthesis. Recently, a team of researchers from Tohoku University and the Toyohashi University of Technology developed an efficient method of creating metal plasmas from solid metals under a strong magnetic field in a microwave resonator. The results of their study were published in the AIP Advances journal.
The Process of Creating Metallic Plasmas
The process of creating metallic plasmas from solid metals begins with placing the metal inside a microwave resonator. A strong magnetic field is then applied while the resonator is energized with a microwave beam. This will cause the electrons to leave their orbit and form a plasma state. The researchers explain that the high-frequency magnetic field causes the microwave beam to be reflected off the metal sample and the energy is then converted into heat.
The team of researchers says that the advantage of this method is that it can produce plasmas with higher energy and a more uniform temperature than other methods. This is due to the fact that they are using a microwave resonator, which uses microwaves to heat up the sample and create plasmas.
Applications of Metallic Plasmas
The metallic plasmas created through this method can be used in various applications. One of the main applications is metal extraction from ores. The high-energy plasmas produced by this method can be used to efficiently extract precious metals from ore. Additionally, the plasmas can be used in welding, as the plasma can melt metal labor, which allows for more precise welding operations. The plasmas can also be used in chemical synthesis, as the high-energy environment can speed up the chemical reactions.
Conclusion
The research team from Tohoku University and the Toyohashi University of Technology have developed an efficient method of creating metallic plasmas from solid metal under a strong magnetic field in a microwave resonator. This method has various advantages and can be used in various applications, such as metal extraction from ores, chemical synthesis and welding. The results of their study were published in the AIP Advances journal.
