Abstract: The experimental studies have shown that, during evaporation of coarsely dispersed carbonyl nickel, a nanodispersed powder of high purity can be obtained, which is promising for use in different technological applications. The process has a high efficiency and a relatively high output (of the order of 100 g/h). The specific feature of the synthesis is the separation of obtained nanoparticles into two fractions with average sizes of approximately 100 and 200 nm. The computer analysis of the system evolution has demonstrated that this separation can occur as a result of the aggregation of the initial clusters of sufficiently large sizes.
