Organic Silanes and Titanates as Processing Additives for Injection Molding of Ceramics

Organic silanes and titanates were added to a system of polyethylene and silicon nitride intended for injection molding and to a model system of paraffin oil and silicon nitride. The effect of the additions on viscosity was studied. Results from the model system agree comparatively well with the results from the system intended for injection molding. The model system can be used for screening tests. A glycidoxytrimethoxysilane reduces the viscosity of the polyethylene‐silicon nitride system. In combination with tetrabutyl titanate, the effect is more pronounced.
