Abstract
A coating solution, useful in the process of coating a substrate with an alumina film, can be formed by adding to an alkali aluminate solution a sufficient quantity of an alumina gel which is a precipitate formed by the reaction of aluminum sulfate with aqueous ammonium hydroxide at a pH of between about 6 and 8. The added alumina gel effects a coating of an adherent alumina trihydrate film on a substrate upon the contacting of the substrate with the coating solution.
