Phase composition and morphology of products of combustion of ferrosilicon in nitrogen / L. N. Chukhlomina [et al.]
Уровень набора: Glass and Ceramics = 2007Язык: английский.Страна: .Резюме или реферат: The results of a study of silicon nitride phase formation in combustion of ferrosilicon in gaseous nitrogen are reported. It was shown that formation of α-or β-modifications of silicon nitride is basically determined by the composition of the batch for self-propagating high-temperature synthesis. When ammonium chloride was added to the initial ferrosilicon, a combustion product with a high (up to 80 %) α-Si3N4 content is formed, while dilution with the final product and magnesium fluoride results in predominant (more than 95 %) formation of β-Si3N4. The particle size and shape are a function of the conditions of synthesis and are primarily determined by the temperature and the additives incorporated in the initial alloy.Примечания о наличии в документе библиографии/указателя: References: p. 65.Аудитория: .Тематика: труды учёных ТПУReferences: p. 65
