Effect of Addition Procedures of Yttria on Slip Casting of Titanium Nitride

Abstract

The effect of the addition of yttria was investigated on the preparation of titanium nitride aqueous slurry by ball-milling. Slip casting was carried out using the prepared slurries, and the effect of the slurry characteristics on forming and sintering behavior was studied. The amount of the dispersant to minimize the viscosity of the slurry increased with increasing both amount of yttria and milling time. A high density compact with homogeneously dispersed yttria could be prepared by slip casting the slurry prepared by long time milling. Titanium nitride sintered body could also be successfully prepared by firing in nitrogen atmosphere.
