Conclusion
This article has reviewed the generation of ceramic powders by chemical precipitation methods, the generation of ceramic powder suspensions, and the processing of ceramic powders to make ceramic green bodies. These methods are used to produce chemically pure ceramic powders of narrow particle size distributions. Agglomeration must be prevented by electrostatic or steric means with single component suspensions. With multicomponent suspensions, flocculation is often performed to lock in the well mixed nature of the suspension, preventing segregation due to differences in particle size, shape, and density. During green-body formation, large amounts of liquid must be removed while packing the particles uniformly. The fundamentals of greenbody formation are discussed with special attention to the details of particle packing in the green body since its microstructure has such a large influence on the final sintered microstructure and the mechanical and electrical properties of the piece.
