Abstract

1. Способ получения нанодисперсных оксидов металлов из водных растворов нитратов металлов, заключающийся в том, что проводят непрерывное взаимодействие, в проточном режиме, нитратов металлов с карбамидом в молярном соотношении 2 моль нитратных групп соли металла к 1 моль карбамида, при этом реакционную среду подвергают воздействию микроволнового излучения.2. Устройство для осуществления способа получения нанодисперсных оксидов металлов, включающее емкости для исходных реагентов, смеситель, реактор, конденсатор и бункер для приема продуктов, отличающееся тем, что реактор представляет собой микроволновую печь, в которую вставлен цилиндр, торцевые части которого выведены за пределы микроволновой печи.1. The method of obtaining nanosized metal oxides from aqueous solutions of metal nitrates, which consists in the fact that they conduct continuous interaction, in a flow mode, of metal nitrates with urea in a molar ratio of 2 mol of nitrate groups of a metal salt to 1 mol of urea, while the reaction medium is exposed microwave radiation. 2. A device for implementing a method for producing nanodispersed metal oxides, including containers for the starting reagents, a mixer, a reactor, a condenser and a hopper for receiving products, characterized in that the reactor is a microwave oven, into which a cylinder is inserted, the end parts of which are removed outside the microwave oven.
