Abstract

Способ получения кремния из силицида магния, включающий получение силицида магния и термическое разложение силицида магния, отличающийся тем, что получение силицида магния осуществляют в смеси диоксида кремния с магнием, которая соответствует стехиометрическому соотношению 1:1 для восстановления диоксида кремния до силицида магния, процесс термического разложения силицида магния осуществляют термической обработкой в кислородсодержащей атмосфере при температуре выше 650°С.A method of producing silicon from magnesium silicide, including the preparation of magnesium silicide and thermal decomposition of magnesium silicide, characterized in that the preparation of magnesium silicide is carried out in a mixture of silicon dioxide and magnesium, which corresponds to a 1: 1 stoichiometric ratio for the reduction of silicon dioxide to magnesium silicide, thermal decomposition magnesium silicide is carried out by heat treatment in an oxygen-containing atmosphere at a temperature above 650 ° C.
