Abstract
The paper shows results of structure and morphology research of silica nanopowder obtained from high silica 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 (TEM) was used to study the morphology. BET analysis was used to study the surface. Synthesized agglomerated nanoparticles have a spherical shape and size distribution in the range of 10-300 nm
