Abstract
1. Способ получения субмикронных и наночастиц алюминия, покрытых слоем оксида алюминия, в котором алюминий испаряют с поверхности капли, разогретой и подвешенной в поле высокочастотного индуктора, каплю непрерывно сверху подпитывают алюминиевой проволокой, реакцию окисления частиц алюминия проводят в смеси инертного газа с кислородом, а полученный порошок улавливают фильтром, отличающийся тем, что, с целью расширения области применения способа и создания товарного продукта для использования в качестве наполнителя в составе композитных теплопроводящих диэлектриков, кислород вводят в поток инертного газа в области, лежащей ниже уровня поверхности капли. ! 2. Способ по п.1, в котором толщину оксидного покрытия регулируют путем изменения положения места ввода кислородсодержащего газа. 1. A method of producing submicron and aluminum nanoparticles coated with a layer of aluminum oxide, in which aluminum is evaporated from the surface of a drop heated and suspended in the field of a high-frequency inductor, the drop is continuously fed from above with an aluminum wire, the oxidation reaction of aluminum particles is carried out in a mixture of inert gas with oxygen, and the resulting powder is captured by a filter, characterized in that, in order to expand the scope of the method and create a marketable product for use as a filler in the composite x thermally conductive dielectrics, oxygen is introduced into the inert gas stream in the region lying below the surface level of the droplet. ! 2. The method according to claim 1, in which the thickness of the oxide coating is controlled by changing the position of the input point of the oxygen-containing gas.
