Powders with fillings: new technology will accelerate the creation of materials for microelectronics
Scientists have created a new method for the production of powder materials for additive technologies, microelectronics, chemical industry and aerospace industry. Its uniqueness lies in the fact that a specialized installation creates powders with certain characteristics: particle size, shape, composition. Such powder materials play a key role in the high-tech industry, experts emphasized. And the new technology will help reduce the dependence of such industries on imports. Read more about the innovation in the Izvestia article.
Plasma chemical synthesis of powders
The Federal Research Center for Chemical Physics and Medical Chemistry of the Russian Academy of Sciences, as part of the NTI competence centers, presented a project for the production of powder materials for additive technologies, microelectronics, the chemical industry and the aerospace industry. The presentation took place within the framework of the Venture Laboratory.The hub of the Archipelago 2025 design and educational intensive.
The uniqueness of the method lies in the fact that a specialized installation creates powders of certain characteristics — it can be used to adjust the particle size, shape and composition. The purity of the resulting materials depends on the purity of the initial reagents, the authors of the project told Izvestia. With their proper quality, the method of plasma chemical synthesis of powders for various applications shows good results.
— The advantage of the technology is to obtain high-purity materials, which are necessary for microelectronics. The product of the project at the first stage will be powders with specified characteristics," Lyubov Shmygaleva, head of the Laboratory of Materials Technologies and Devices of Electrochemical Energy Sources, told Izvestia.
The method used is plasma chemical synthesis, in which chemical reactions take place in low—temperature plasma, which makes it possible to obtain finely dispersed powders. The technology makes it possible to obtain powders of various materials, such as nitrides, carbides, borides and oxides, with a high rate of formation of new particles.
Currently, for example, there are no manufacturers of powders for lithium-ion batteries in Russia, the developers said. Therefore, at the first stage, they plan to produce and sell the silicon-containing powders needed for them. The material obtained by the new method is not inferior in characteristics to world analogues at a lower price, the technology developers noted.
Scientists have patented the technology, and in the future they will be able to offer licenses for modular plasma chemical synthesis plants capable of operating in different industries, depending on the desired properties of the powders produced.
— We have created an installation with a capacity of up to 5 kW, the only one in the CIS. A more powerful prototype is also being developed — up to 50 kW. All nodes will be of domestic production. The project develops the country's technological leadership," said Lyubov Shmygaleva.
In the future, such installations will allow for more complex connections. For example, silicon particles coated with oxide. And in the future, their capacity can be increased to 1 MW.
The total investment in the project will amount to 392 million rubles, said Yaroslav Fedoseev, Head of Strategic Communications at the NTI Foundation.
Import substitution in the high-tech industry
Such specialized installations are definitely needed by scientists and will be in demand in our country, said Grigory Zyryanov, professor of the UrFU Department of Organic and Biomolecular Chemistry. For example, the shape and size of the particles affects the reaction rate and the effect of the substance.
— So, spherical particles (under the condition of contact on the surface) interact with each other to a limited extent due to the small area of interaction. Particles of a different shape, for example, cubic, tetrahedral and others, will interact better due to the higher contact surface, respectively, the reaction will take place faster, - said the specialist.
In addition, if the catalysts are ground in a certain way, they will have a high contact surface, which means a better effect (for example, in the case of nanocatalysts). If we talk about medicine, then the finely ground substance of the drug will certainly be absorbed better, said Grigory Zyryanov.
Russia remains dependent on imports, equipment and raw materials for the production of nano- and micropowders with specified characteristics, Leonid Drobyshevich, an NTI technology expert, told Izvestia. Powder materials play a key role in the high-tech industry. Powders of a certain quality are needed for different industries.
— The advantage of the project is that the production facility is a universal modular platform. In other words, it produces different types of powders and will meet the needs of many industries, from energy to medicine," the expert noted.
There are really few such materials in Russia, said Evgeny Alexandrov, director of the Center for Digital Materials Science: New Materials and Substances at the Bauman Moscow State Technical University.
"The technology is also promising for researching ways to produce new materials, including high—entropy alloys (metal alloys in which five or more elements are mixed in approximately equal proportions) and catalysts," the expert emphasized.
The intensive Archipelago 2025 is being held from August 7 to 17 at the Skolkovo Innovation Center as part of the International Forum on the Development of Unmanned Systems "Unmanned Systems: Technologies of the Future".
