Abstract

Описан способ модификации характеристик поверхности оксида алюминия, включающий следующие стадии: (i) получение водной смеси, включающей одну массовую часть оксида алюминия и мономерное или полимерное соединение алюминия, соответствующее 0,001-0,1 мас.ч. от содержания алюминия; (ii) приведение этой смеси в равновесие в течение по меньшей мере 5 мин; (iii) повышение рН смеси до 6-8 и (iv) сушку указанной смеси, причем указанный способ включает дополнительную стадию повышения рН смеси до 3,0-5,0 между стадиями (i) и (ii), когда указанное соединение алюминия является мономерным.
