N2 - This article discusses the synthesis of hollow Al2O3 nanoparticles via electric arc spraying and subsequent material calcination in air. The effect of buffer gas pressure on the size and thickness of the synthesised hollow nanoparticle enclosure is investigated. Based on experimental data and numerical modelling data for the respective processes, a mechanism for the formation of various-sized nanoparticles based on changes in the residence time of carbon is proposed.
