At KTU, researchers complete 80 percent of' Super magnet ' production
Karadeniz Technical University (KTU) in the research group conducted within the scope of magnetic materials, Neodymium super strong magnet in the sector called electromagnetic (Nd), iron (Fe) and boron (B) obtained from the component of the production of NdFeB magnets 80 percent completed.
KTU Faculty of Engineering Department of Metallurgy and Materials Engineering Professor Dr. Sultan Ozturk told AA correspondent that they have been studying magnetic materials for about 15 years.
Ozturk, who is also responsible for the Magnetic Materials Research Group, stated that they continue their work with undergraduate, master and doctoral theses from the university, research support from TUBITAK and the National boron Research Institute.
Öztürk stated that they have achieved remarkable, promising results thanks to years of experience, developing technology and infrastructure investments, and that the team of 7 people has been continuing the work continuously to finalize the research.
Ozturk, pointing out that they are working on three groups of materials, said: "for many years, we have been working on a magnet based on neodium, iron and boron, the name of which is mentioned in the market as a super magnet. The second group of material we produce is strontium hexaferrite based, that is, ceramic magnets. In the third group, we continue to work on the FE-B-based strip, which is also used as a sensor material." said.
Super magnet, a very strong type of magnet, the name of which comes from here emphasizing Öztürk, " these magnets have a history dating back to 1984, since the date of discovery is a magnet that has been constantly developed. A magnet with elements of iron, neodium, boron. As far as I know, we do not produce it in Turkey, we use it by importing it. One of the reasons why this does not happen is that the raw material is not in Turkey. We have about $ 30 million a year in imports., "he said.
Ozturk noted that the automotive sector is at the beginning of the use of super-strong magnets, saying: "these are very strong magnets. Especially in engines, especially in electric car engines, which are currently on the agenda Dec. It is used in generators and applications requiring large torque. So these are important magnets."used the phrase.
"We're past the hard part"
Describing that they produce magnet powder as the first stage in production, Öztürk made the following assessment:
"The most important element in this magnet, the neodium element, is extremely reactive, that is, an oxidized element affected by air. An element that deteriorates from contact with a small air, so the production of this magnet requires some high-tech devices. The production of this magnet must be in a specially tuned area that we call a controlled atmosphere. The method we use in production is Powder Metallurgy method. The process applied here is to first produce the powder of this magnet. We have to produce this without oxide, bright, we have achieved this."
Ozturk noted that the second stage is the processing of the obtained substance in a controlled atmosphere to reach a certain powder size.:
"It needs to be reduced to 3-5 microns by grinding in a controlled heat environment; we also made it. Then it needs to be pressed, shaped under a magnetic field. Here we are at the stage where there should be binding between the powders, which we call sintering, which is this final stage. This, in turn, is a process that must be done in a controlled atmosphere and there must be some processes. We're past the hard part. We have achieved approximately 80 percent of the production of the Super magnet. We have reached the final stage, our work continues, I have no doubt that we will succeed."
Ozturk, who believes that producing a super magnet will make a great contribution to Turkey, said: "the Super magnet is used in many medical devices. From the MRI machine to the generators, to the automobile engines. Especially if Turkey produces its own car, the need for these magnets will increase more. Because as our production gets richer, as we diversify, our need will increase."used the phrase.
Öztürk emphasized that production parameters were put forward and said, "industrialists who are interested in this issue, private sector organizations take them, we cooperate, produce them. And we'd be very proud of that., "he said.
