Ceramic materials

The properties of ceramic components are decisively dependent on the quality of the starting powders: in addition to the particle size distribution and shape, the important parameters are the BET surface area and density.Further the type and performance of the molding process is essential: e.g. in the case of a wet process (suspension route), the slurry properties influence the properties of the green body in addition to the real process parameters. The essential quality features here are the stability of the suspension against sedimentation and agglomeration, whereby the zeta potential plays an important role in electrostatically or sterically stabilized systems. Moreover, the rheological properties are crucial for shaping of the bodies.Optimized properties of the green body, in particular a proper distribution and size of the pores for the sintering process and, of course, the shape stability, are absolutely required for an ideal ceramic end product!
