Реферат:
Variations in the functional composition under the action of accelerated electrons was analyzed for the surface of oxide materials (A-175 Aerosil and barium titanate). The dependence of the content of Lewis and Broensted sites and their mutual conversion on the absorbed dose exhibit extremal behavior. The mechanisms of the variation of the functional composition of the surface were established to be related to the following rearrangements of the surface layer structure under the action of increasing absorbed dose. At doses below 100 kGy, the physically sorbed molecules of water dissociate into radicals and react with siloxane groups to form hydroxyls. At higher doses, a dehydration of the surface occurs. Electron-beam processing was demonstrated to be a promising method for controlled modification of the surface of oxides.
