Novosibirsk scientists have learned in seconds to obtain high-strength ceramics

Preparation in this case takes much more effort and time than the process itself. The industrial accelerator of the Institute of Nuclear Physics will work on the creation of a new type of ceramics of increased strength and heat resistance. To synthesize a material with unprecedented properties will help fast electrons. The study is conducted under a grant from the Russian Science Foundation together with Tomsk colleagues. “This is the only scientific installation in Russia capable of releasing an electron beam into the atmosphere at energies of 1.4-2.5 megaelectronvolts, the beam power is about 70 kilowatts,” explained researcher at the Institute of Nuclear Physics SB RAS Evgeny Domarov. The output is a beam with a diameter of two millimeters, very powerful and dense - what it takes for the five original metal oxides from the mixture of powders to turn into a single whole. Once the installation is ready to start, you can only observe the process remotely through the camera. Just a second the beam affects the powder, and that is enough. “The mixture is heated above the melting point, the components are mixed evenly, the alloy is formed. In the crystal lattice of the material, the atoms occupy a disorderly position, as a result of which the material has a high hardness, says Mikhail Golkovsky, senior researcher at the Institute of Nuclear Physics of the SB RAS. Traditional methods of obtaining ceramics take hours or even days. The new technology saves both time and energy. The material can be used in industry from electronics to medicine and aviation, applied to the blades of gas turbine engines. But the research isn't finished yet. Tomsk colleagues, who select the composition and proportions of the original powder, in search of new options for different requests and tasks.
