For the deposition of the layers, the starting powders were ground through wet ball milling, by adding the appropriate amount of solvent (2-propanol) and dispersant, for 24 h. The deposition was carried out at room temperature, using an airbrush (Iwata eclipse HP-BCS) operated at an angle of 90° with respect to the supporting plane.
Current practices employ a wet media milling process (also known as: bead milling, wet pulverization, wet comminution, ball milling, wet grinding, micronization), in which initial CaCO 3 particles sized on the order of 10s of µm are broken down to the required median particle diameter of d 50 < 3 µm. This task is cumbersome, to say the …
