Abstract
1. Способ синтеза полых наночастиц γ-AlOв плазме электрического разряда, включающий откачивание вакуумной камеры, наполнение ее инертным газом, зажигание электрической дуги постоянного тока между подвижным графитовым электродом и неподвижным композитным (металл-углеродным) электродом, представляющим собой графитовый стержень с просверленной по центру полостью, и распыление композитного электрода, отличающийся тем, что в плазме электрического разряда в атмосфере инертного газа распыляют металл-углеродный композитный электрод, в просверленной по центру полости которого установлена проволока из алюминия, при этом весовое соотношением C:Al составляет 15:1, затем выполняют отжиг синтезированного в плазме электрического разряда композиционного материала, представляющего собой углеродную аморфную матрицу, в которую внедрен высокой степени дисперсности алюминий, частично или полностью в карбидном соединении, в кислородсодержащей среде при атмосферном давлении и температуре 400-950°C в течение одного часа.2. Способ по п.1, отличающийся тем, что инертный газ выбирают из группы: He, Ne, Ar, Kr,Xe.1. A method for the synthesis of hollow γ-AlO nanoparticles in an electric discharge plasma, including pumping out a vacuum chamber, filling it with an inert gas, igniting a direct current electric arc between a movable graphite electrode and a stationary composite (metal-carbon) electrode, which is a graphite rod with a center drilled cavity, and spraying a composite electrode, characterized in that in a plasma of an electric discharge in an inert gas atmosphere a metal-carbon composite electrode is sprayed in an aluminum wire mounted in the center of the cavity, the weight ratio of C: Al being 15: 1, then annealing the plasma-synthesized electric discharge of the composite material, which is a carbon amorphous matrix, into which a high degree of dispersion aluminum is embedded, partially or completely in a carbide compound, in an oxygen-containing medium at atmospheric pressure and a temperature of 400-950 ° C for one hour. 2. The method according to claim 1, characterized in that the inert gas is selected from the group: He, Ne, Ar, Kr, Xe.
