The effect of dispersion in alumina slurry on the development of grain orientation during the sintering process

This paper demonstrated the effect of dispersibility in alumina slurry on the change in the distribution of orientation for the particle-oriented compact during a sintering process. The orientain was developed with increasing the sintering temperature. The variation of density and microstructure with sintering temparature clarified that both densification and grain growth contributed to development of the oriented structure. The difference in slurry dipersion affected the degree of orientation in sintered bodies. This result suggests that proper dispersion in slurry is necessary to obtain a material with highly oriented structure when it needs forming methods involving slurries and subsequent sintering.
