摘要：

An alumina hydrosol is synthesized by controlled hydrolysis of an aqueous solution of aluminium chloride using the thermal decomposition of urea. After dialysis, a transparent and fluid colloidal dispersion is obtained which can be used to prepare alumina coatings. The characteristics of the sol, the structure and the thermal evolution of the resulting alumina gels are studied. (C) 1999 Elsevier Science B.V. All rights reserved.
