Оптимальная температура сушки 120–160°С.</p><p>Формирующиеся в приведенных условиях покрытия состоят из оксидов церия CeO2, Ce2O3, а также оксид алюминия Al2O3. Введение сложного эфира галловой кислоты (в количестве 0,5–1,5 г/л) в рабочий раствор приводит к изменению химического состава формирующихся покрытий, а именно к исключению в его составе соединений нем CeO2.

The addition of a tannin (in an amount of 0,5-1,5 g/l) to the working solution leads to a change in the chemical composition of the forming coatings, namely, to the exclusion of CeO2 compounds in their composition.
