This completely new technology for the production of powders with a size from a few hundred nanometres up to individual micrometres using cavitation is the result of the work of the Materials Characterization and Advanced Coatings research group at CEITEC and the Fluid Engineering Department of the Energy Institute of FME BUT. “In its development we use the cavitation, which is essentially a negative phenomenon that causes permanent and irreversible damage of hydromachines. The technology itself arises from the formation of decavitated matter from ferromagnetic materials in a cavitational cloud and its retention in a permanent magnetic or electromagnetic field,” stated team leader and project author Ladislav Čelko, from CEITEC BUT, describing the essentials of the research. In this way it is possible to produce powders smaller, that can be achieved with standard available production technologies such as atomisation or milling and grinding, but at the same time of a size one order greater than is achieved using chemical or electrochemical methods.
The award from the Engineering Academy of the Czech Republic is recognition of the outstanding realisation of the technical work and its significant contribution to the development of engineering research in the Czech Republic. The award is presented each year to Czech or foreign individuals and teams for the results of their creative work, where no more than five years have elapsed since it was first carried out or published.
The main aim of the BUT pre-seed Materials Research is the commercialisation of promising technologies and inventions with high potential for application in the field of materials research, including intellectual property protection concerning these technologies and inventions. The total budget for the project is 29 592 418 CZK, with 6.5 million CZK assigned to the project “The Use of Hydrocavitation in the Preparation of Ferromagnetic Nanopowders”.
