Применялись методы динамического рассеяния света, просвечивающей электронной микроскопии, адсорбционный метод. Исследование показало, что при переработке в плазменной установке природного кварцита возможно получать полидисперсные наночастицы диоксида кремния с распределением 10–300 нм, средним размером 30 ± 7 нм, удельной поверхностью 71 ± 4 м2/г. При этом частицы склонны к агломерации в среднем по десять частиц. Для исследуемого порошка установлен дзета-потенциал –54 ± 9 мВ, что является полезным с прикладной точки зрения при планировании многокомпонентных систем на его основе. Исследуемый порошок может применяться в качестве упрочняющей добавки для изготовления строительных материалов с повышенными эксплуатационными характеристиками для создания объектов специального назначения.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of a comprehensive study of the particle morphology, size distribution, average size, specific surface area and agglomeration of SiO2 nanoparticles obtained by plasma technology from natural high-silica raw materials (quartzite). The dynamic light scattering, transmission electron microscopy, and nitrogen adsorption techniques are used. It is shown that using the plasma source, polydisperse silica nanoparticles with the distribution of 10–300 nm can be obtained with the average size of 30 ± 7 nm and specific surface area of 71 ± 4 m2/g from natural quartzite. The average agglomerate consists of about 10 particles. The zeta potential varies from –54 to 9 mV for the powder, which can be useful in planning multicomponent systems. The investigated powder can be used as a hardening additive for the manufacture of building materials with improved performance for the creation of specialpurpose objects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанопорошок диоксида кремния</kwd><kwd>плазменно-дуговой метод</kwd><kwd>динамическое рассеяние света</kwd><kwd>просвечивающая электронная микроскопия</kwd><kwd>адсорбционный метод</kwd><kwd>морфология</kwd><kwd>распределение по размерам</kwd><kwd>удельная поверхность</kwd><kwd>агломераты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silica nanoparticles</kwd><kwd>plasma technology</kwd><kwd>dynamic light scattering</kwd><kwd>transmission electron microscopy</kwd><kwd>adsorption method</kwd><kwd>morphology</kwd><kwd>particle size distribution</kwd><kwd>specific surface area</kwd><kwd>agglomerates</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bak M., Molnár F., Németh R.
