Article Preview

The ceramic injection molding feedstock of Al2O3-SiC nanocomposite were prepared and studied in detail. Three ways of surface modification including surfactant pre-coating, surface emulsion polymerization and surface low temperature plasma polymerization were used to modify the surface of SiC powders in order to reduce the agglomeration, improve the dispersion and the compatibility with organic media. CIM feedstock with different SiC content and solid loading were prepared through mixing surface modified SiC powders with Al2O3 powders and organic binders. The effect of three ways of surface modification on the viscosity of CIM feedstock were studied and the way of surface emulsion polymerization developed the best action in increasing dispersion, reducing viscosity and improving the solid loading of CIM feedstock.
