Abstract:
1. A process for forming thin palladium-based dense film on a substrate comprising: a. providing an uncured ceramic substrate having a surface, wherein the uncured substrate is a mixture of a structural ceramic, a pore former, and a sintering aid; b. providing a pre-colloid mixture comprising a powdered palladium source, carrier fluid, and dispersant; c. agitating the pre-colloid mixture to form a colloid; d. pumping the colloid mixture to an ultrasonic atomizing nozzle; e. applying the atomized colloid to the surface of the substrate to form a palladium based layer having a thickness from about 1 μm to about 100 μm on the substrate; and f. heating the substrate and colloid mixture to form a palladium coating on the substrate.
