Abstract
A process of producing an organically modified metal oxide wherein an aqueous slurry of a metal oxide which can be peptized in the presence of an acid is admixed with an aqueous slurry of an organo silane having the formula RySiX4-y, the mixture of the aqueous slurry and the organo silane being thermally aged to produce a colloidial metal oxide sol which can be dried to produce a powder which is readily dispersible in polar compounds such as alcohols, water and the like.
Claims10
A process for treating a metal oxide comprising:
- forming an aqueous slurry of a metal oxide having the formula MaOb, said metal oxide being susceptible to peptization in the presence of an acid;
- mixing with said aqueous slurry an organo silane having the formula RySiX4-y wherein R is an organic moiety, X is a moiety which produces an acid anion in the presence of water and y is from 1 to 3 and provided that where y is 2 or 3, R can be 2 or 3 of the same organic moiety or 2 or 3 different organic moieties;
- and
- subjecting the mixture of said aqueous slurry and said organo silane to thermal aging to produce a colloidial metal oxide sol.
