Abstract:
1. A method of preparing a test article having an array of inorganic compositions comprising the steps of: casting a substrate slurry in a mold of a selected shape to form a substrate, wherein said substrate slurry comprises at least an inorganic powder, a solvent, and a polymerizable monomer, wherein a surface of said substrate includes a plurality of cavities, wherein each cavity in said plurality of cavities is separated from one another at least in one direction; removing said substrate from said mold; depositing a first test slurry into a first cavity among said plurality of cavities and a second test slurry into a second cavity among said plurality of cavities, wherein each of said first and second test slurries comprises at least a powder, a solvent, and a polymerizable monomer, wherein said first and second test slurries differ from each other in at least one compositional characteristic, and wherein said first test slurry does not directly contact said second test slurry; and polymerizing said polymerizable monomer in each of said first and second test slurries to form at least one first test material portion in said first cavity and at least one second test material portion in said second cavity, wherein each of said at least one first test material portion and said at least one second material portion differ from each other in at least one compositional characteristic.
