Abstract
Studies of the structure formation features of composite inorganic materials formed on the basis of silicon dioxide, namely, pyrogenic silica of the A-380 brand (technical name – aerosil). The main purpose of the research was to study the possibility of improving the uniformity of the distribution of injected dopants on the surface of SiO2 globules forming the xerogel framework. This goal was achieved due to the uniformity of the distribution of alloying salts (for example, copper nitrate) at the stage of sol formation, which was converted to the state of xerogel as a result of sequential heat treatment in a controlled gas environment (air or dried hydrogen). The final shape of the samples was either micro-powders or tabletshaped blanks obtained on their basis – with a diameter of about 12.5; 2.50; 30; 40 and 80 mm and a phase composition of SiO2 : CuO and SiO2 : Cu°.
Supporting agencies: The work was carried out within the framework of task 2.2.6 of the state research program “Convergence-2025” (subprogram “Microcosm, plasma and the Universe”), funded from the republican budget for state research programs for 2021–2025 in the Republic of Belarus.
