Abstract
Способ получения двойных оксидов (алюминатов щелочных и редкоземельных металлов) в процессе горения конденсированных составов при частичном или полном улетучивании одного из компонентов, включающий приготовление реакционно-способной шихты, содержащей окислитель (безводные или гидратированные нитраты и нитриты металлов) и горючее (алюминий), загрузку полученной смеси в замкнутый реактор, разогрев материалов до инициирования реакции самораспространяющегося высокотемпературного синтеза (СВС) и выдержку в режиме горения, отличающийся тем, что в качестве окислителя используют фосфаты кальция, а в качестве продуктов реакции получают алюминаты кальция и фосфор.A method of producing double oxides (alkali and rare-earth aluminates) during the combustion of condensed compounds with partial or complete volatilization of one of the components, including the preparation of a reactive charge containing an oxidizing agent (anhydrous or hydrated metal nitrates and nitrites) and fuel (aluminum), loading the resulting mixture into a closed reactor, heating the materials to initiate the reaction of self-propagating high-temperature synthesis (SHS) and holding in the combustion mode, characterized it, in that the oxidant used calcium phosphates, as well as reaction products obtained calcium aluminates and phosphorus.
