Various binder systems have been used in ceramic injection molding, which can be classified into five types (i) thermoplastic compounds, (ii) thermosetting compounds, (iii) water-based systems, (iv) gelation systems, and (v) inorganics. Among these, thermoplastic compounds are the most widely used and understood, which are mainly commercial polymers. The ratio of powder to binder is a key parameter.

Preceramic polymers have the potential to improve traditional ceramic processing methods (2). In particular, ceramic injection molding may be enhanced by the replacement of organic binders with thermosetting polysilazanes. Table II compares the attributes of the two binder systems.

The test results show that - conqrared to the matrix polymer - the viscosity of the conqxrund is higher, but still in the margin of other unfilled polymers due to the effect of the metal melt (Fig. 2). Highly solidly filled polymers -e. g. a ceramic injection molding (CIM) feedstock - show a higher-viscous behavior. A variation of temperature has just minor effects on the mrtal/polymer melt viscosity.
