Abstract

В изобретении способ получения оксида фосфора(V) включает образование предварительных агломератов, содержащих частицы фосфатной руды, частицы углеродистого материала и частицы диоксида кремния, нагревание предварительных агломератов в восстановительной или инертной атмосфере до температуры обжига, составляющей от более чем 900 до менее чем 1180°С, и выдерживание температуры обжига в течение 15 мин или более. Способ включает образование исходных агломератов и увеличение прочности при сжатии исходных агломератов до более чем 25 фунт-сил (111 H) с использованием нагревания, причем исходные агломераты проявляют молярное соотношение кальция и диоксида кремния, составляющее менее чем 1, и молярное соотношение диоксида кремния и суммы кальция и магния, составляющее более чем 2. Восстановительный слой печи образуется с использованием исходных агломератов, производится печной отходящий газ, и оксид фосфора(V) собирается из печного отходящего газа.
