Разработка сложных композиционных материалов на основе MgO, получаемых коллоидным методом

Abstract

Рассмотрены технологические приемы формирования чистых и композиционных материалов состава MgO : SiO2 : CaO : BaO, полученных с использованием коллоидных методов. Методом сканирующей электронной микроскопии были изучены структурные превращения, происходящие в синтезированных ксерогельных заготовках при их термообработке на воздухе в диапазоне температур от 400 до 600 °C. При температуре 400 °C интервал распределения по размерам первичных зерен составляет от 37 до 56 нм, при 500 °C – от 33 до 74 нм, а при 600 °C – от 40 до 64 нм. Рентгенофазовый анализ показал, что сформированный нанокомпозит имеет кристаллическую структуру с равномерным распределением примесей. EDX исследования подтвердили расчетный исходный состав полученного материала. Из полученного композита сформированы диски диаметром 13, 20 и 40 мм для проведения экспериментов по очистке воды от загрязнений нефтепродуктами. Technological approaches to the formation of pure and composite materials with the composition MgO : SiO2 : CaO : BaO, obtained using colloidal methods, are considered. Structural transformations occurring in the synthesized xerogel blanks during their heat treatment in air at temperatures ranging from 400 to 600°C were studied using scanning electron microscopy. At 400 °C, the size distribution of primary grains ranges from 37 to 56 nm, at 500 °C – from 33 to 74 nm, and at 600 °C – from 40 to 64 nm. X-ray phase analysis showed that the formed nanocomposite has a crystalline structure with a uniform distribution of impurities. EDX studies confirmed the calculated initial composition of the obtained material. Disks with diameters of 13, 20, and 40 mm were formed from the obtained composite for experiments on water purification from petroleum product contamination.
