A process for coating a solid substrate with a layer of barium metaplumbate includes steps of forming a layer of lead oxide on the substrate, if not already present, and then reacting this layer with a barium salt at an elevated temperature to form a layer of coating of barium metaplumbate. Reaction temperature is a key aspect of this process, along with use of a barium salt which will react at the temperature selected. In particular, the reaction temperature must be sufficiently high to allow the reaction to proceed, but lower than the melting point of the substrate. The described process eliminates the need to preform BaPbO3 prior to coating and can be conducted at a much lower range of temperatures than prior processes. |
