Изготовленные из шихты I состава образцы имели следующую структуру: базальтовое волокно (37 мас.%) + муллитокремнеземистое волокно (19 мас.%) + модификатор Al2(SO4)3 в качестве связки (11 мас.%) + порообразователь (19 мас.%) + фарфор в качестве упрочнителя (4 мас.%) + пластификатор (11 мас.%); II состава: базальтовое волокно (52 мас.%) + SiO2 (15 мас.%) + порообразователь (1 мас.%) + фарфор (алюмосиликат) в качестве упрочнителя (6,5 мас.%) + пластификатор (КМЦ, 6,5 мас.%) + известняковая мука (карбонат кальция, CaCO3, 19 мас.%). Термоциклирование проводилось в трех диапазонах температур 750–770 °С, 1025–1075 °С, 1070–1090 °С с целью получения определенных структуры и свойств композитов, спрессованных под давлением 20, 40 и 60 МПа. Для контроля морфологии поверхности, изменения фазового состава, аморфности и параметров тонкой структуры, пористости, проницаемости и прочностных свойств проводили оценку образцов на каждом цикле процесса.  На  основе  установленных  закономерностей  структурообразования  предложены  режимы  формирования порового пространства с сохранением пористости не ниже 45 %, прочности – 5–25 МПа, усадки в процессе спекания – не более 20 %. Исследованные композиционные материалы могут быть использованы для создания фильт-  рующих элементов систем разделения, очистки, преобразования жидких и газообразных сред. </p></abstract><trans-abstract xml:lang="en"><p>The results of studying the structure and properties of two compositions of porous composite materials of the CaO–MgO–FeO(Fe2O3)–Al2O3–SiO2 system based on basalt fiber formed during thermal cycling are presented. The samples made from the mixture of composition I had the following structure: basalt fiber (37 wt.%) + mullite-silica fiber (19 wt.%) + modifier Al 2(SO4)3 as a binder (11 wt.%) + blowing agent (19 wt.%) + porcelain as a hardener (4 wt.%) + plasticizer (11 wt.%); II composition: basalt fiber (52 wt.%) + SiO2 (15 wt.%) + blowing agent (1 wt.%) + porcelain (aluminosilicate) as hardener (6.5 wt.%) + plasticizer (CMC, 6.5 wt.%) + limestone flour (calcium carbonate, CaCO3, 19 wt.%). Thermal cycling was carried out in three temperature ranges of 750–770 °C, 1025–1075 °C, 1070–1090 °C in order to obtain certain structure and properties of composites pressed under pressure of 20, 40 and 60 MPa. To control surface morphology, changes in phase composition, amorphousness and fine structure parameters, porosity, permeability and strength properties, samples were evaluated at each process cycle. On the basis of established patterns of structure formation, modes of formation of pore space are proposed with preservation of porosity not lower than 45 %, strength 5–25 MPa, shrinkage in the process of sintering – not more than 20 %. The studied composite materials can be used to create filter elements of systems for separating, cleaning, converting liquid and gaseous media.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>базальтовое волокно</kwd><kwd>термоциклирование</kwd><kwd>спекание</kwd><kwd>силлиманит</kwd><kwd>анортит</kwd><kwd>пористость</kwd><kwd>проницаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>basalt fiber</kwd><kwd>thermal cycling</kwd><kwd>sintering</kwd><kwd>sillimanite</kwd><kwd>anorthite</kwd><kwd>porosity</kwd><kwd>permeability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках задания 4.1.34 «Разработка и исследование керамических материалов с жесткой системой микрофильтрационных транспортных пор на основе базальтовых волокон» Государственной программы научных исследований «Материаловедение, новые материалы и технологии» на 2021–2025 годы, подпрограмма «Многофункциональные и композиционные материалы».</funding-statement><funding-statement xml:lang="en">the work was performed within the framework of Assignment 4.1.34 “Development and research of ceramic materials with a rigid system of microfiltration transport pores based on basalt fibers” of the State Research Program “Materials science, new materials and technologies” for 2021–2025, the Subprogram “Multifunctional and composite materials”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Витязь, П.
