Abstract
The paper analyzes the changes in elemental impurity composition in the nanopowder synthesis by electron beam evaporation. The conditions in the zone of the initial material evaporation were evaluated. The theoretical justification of the method described of the conditions evaluation at evaporation of high-purity quartz sand in the process of silica nanopowder synthesis by electron beam evaporation. Estimated evaporation temperature due to change of the aluminum and titanium concentrations was 2493 K. The experimental measurement and comparison of the elemental impurity compositions of the vaporized material and the resulting nanopowder for two silica samples had been conducted.
