The rapid hydrolysis of some alkoxides creates problems in alcohol-based sol-gel processes. This paper describes a simple aqueous sol-gel process for the sysnthesis of barium aluminosilicate gels and gel-derived glasses, in which the problem of the rapid hydrolysis of aluminium isoprooxide is solved by a precipitation-peptization process that is cost effective.
