Designs of materials relating to powders and their production process systems using powder simulation are described. The design of piezoelectric ceramics was performed using an estimation model for electromechanical properties (electromechanical coupling coefficient, piezoelectric constant, dielectric constant, elastic compliance) as an example of the material design. The design method allows the design of microstructure of piezoelectric ceramic with desirable electromechanical property. The development of functional materials as electro-ceramics by using the special characteristics of fine particles has become very active. The method gives useful information for the design of production process system of the ceramics. The control of flow behavior of fine particles based on the fully understanding on the flow mechanism of solid particles is important to produce the functional materials as electro-ceramics in industrial processes. Simulation methods for process handling and unit process operation for fine particles is described.
