Mosle hydrogen chloride and prokalivlin at 600 ° C get a product with a specific surface of 220 .. containing 14 wt. tin dioxide.

Пример 4. 10 г аэросйла с удельирй поверхностью 380 и степенью гидратации 16 вес./о обрабатывают парами треххлористого алюмини  при 100° С . После отдувки хлористого водорода и прокаливани  при 700° С получают продукт с удельной поверхностью 280 и содержанием окиси алюмини  16,2 вес./о.Example 4. 10 g of aerosil with a surface of 380 and degree of hydration of 16 wt./about are treated with vapors of aluminum trichloride at 100 ° C. After stripping off hydrogen chloride and calcining at 700 ° C, a product is obtained with a specific surface of 280 and an alumina content of 16.2 w / v.

Таким образом, предлагаемый способ позво; л ет получить высокодисперсные окислы металлов с удельной поверхностью до 350 и регулировать степень дисперсности получаемых окислов металлов от 150 до 350 .Thus, the proposed method allows; It is possible to obtain highly dispersed metal oxides with a specific surface area of up to 350 and to regulate the degree of dispersion of the resulting metal oxides from 150 to 350.
