description | Silicon carbide (SiC) exhibits many functional properties that are relevant to applications in electronics, aerospace,
defense and automotive industries. However, the successful translation of these properties into final applications lies in
the net-shaping of ceramics into fully dense microstructures. Increasing the packing density of the starting powders is one
effective route to achieve high sintered density and dimensional precision. The present paper presents an in-depth study
on the effects of nanoparticle addition on the powder injection molding process (PIM) of SiC powder-polymer mixtures.
In particular, bimodal mixtures of nanoscale and sub-micrometer particles are found to have significantly increased
powder packing characteristics (solids loading) in the powder-polymer mixtures. The influence of nanoparticle addition
on the multi-step PIM process is examined. The above results provide new perspectives which could impact a wide range
of materials, powder processing techniques and applications. |
