РАЗРАБОТКА ТЕХНОЛОГИИ ПОЛУЧЕНИЯ ЧИСТОГО ОКСИДА КРЕМНИЯ ИЗ РИСОВОЙ ШЕЛУХИ
Аннотация
Данное исследование направлено на разработку нового метода получения высококачественного чистого оксида кремния из рисовой шелухи из разных регионов Казахстана. Предлагаемый способ является экологически чистым и использует значительное количество неорганических щелочей и кислот, описанных в литературе, и сравнивается с методом прямого сжигания. Чтобы минимизировать воздействие на окружающую среду, минеральная кислотная фаза была удалена или заменена органической кислотой в предварительной обработке. На основании термогравиметрического анализа была выбрана температура прокаливания 600°C. Средняя чистота образцов оксида кремния, полученных различными методами, находилась в диапазоне от 84,5 до 99,66 %. При использовании экологического метода чистота оксида кремния была высокой, а площадь поверхности достигала 625 м2/г.
