Abstract
A method is disclosed for depositing metal containing films using relatively water-insoluble coating reactants by dispersing said coating reactants in ultrafine powder form into an aqueous medium containing a wetting agent to form an aqueous chemical suspension.
Claims14
A method for depositing a metal-containing film on a substrate which comprises the steps of:
- a. dispersing a relatively water-insoluble coating reactant into an aqueous medium containing a wetting agent to chemically suspend said reactant in said aqueous medium to form an aqueous suspension;
- and
- b. applying said aqueous suspension of chemically suspended coating reactant to a surface of a substrate at a temperature sufficient to cause said coating reactant to react thereby depositing a film on said substrate surface.
