Resumo
The paper presents the structural investigations of hollow, spherical powder obtained from the natural siliceous material using the thermal plasma treatment. Experiments show that the obtained hollow SiO2 particles have almost an ideal spherical shape. Based on the analysis of numerical calculations, thermochemical modeling and results of in-situ experiments, we propose a physical model of formation of hollow, spherical particles produced from agglomerated powder using the thermal plasma flow.
