Study of SiO 2 nanopowder produced by plasma arc method
Abstract The work is devoted to the study of the plasma arc method of obtaining nanosized silicon oxide from natural raw materials from Russian fields, such as diatomite of Kamyshlovsk deposit (Sverdlovsk region), the quartzite of Chupinsk deposit (Republic of Karelia), quartz sand of Tugansk deposi...

| Summary: | Abstract The work is devoted to the study of the plasma arc method of obtaining nanosized silicon oxide from natural raw materials from Russian fields, such as diatomite of Kamyshlovsk deposit (Sverdlovsk region), the quartzite of Chupinsk deposit (Republic of Karelia), quartz sand of Tugansk deposit (Tomsk region). The method of transmission electron microscopy was used to study the morphology. Brunauer-Emmett-Teller method was used to study the surface. The main structural and morphological characteristics of the obtained nanoparticles were determined. The particles of nanoscale SiO 2 obtained by the plasma arc method spherical shape, the size distribution 10–300 nm, the specific surface area 37–71 m 2 ·g −1 . |
