High-energy ball milling is effective in getting well-dispersed slurry. 7−9 The preparation procedure is summarized in Fig. 24.2.First, commercially available PZT powders (APC 850) were high-energy ball milled to get the desired particle size. Secondly, a selected dispersant was added to the milled powders to get the surface-modified powders.
