Abstract

Utilization of common clay in admixtures with quartz and fly ash for fabrication of utility goods and art object is widely in practice. However, slip casting of slurries poses several problems in shaping of green bodies. In the present investigation, Newtonianity of the suspensions were evaluated and an attempt has been made to correlate Newtonian factor ‘n’ with the castability of a slip. Different factors affecting ‘n’ are analysed by rheological investigation of the suspensions. It was found that the suspensions were pseudoplastic in nature with a marked tendency towards Newtonian. The castability of the suspensions were explained in terms of Newtonianity (‘n’ values) of the suspensions. The results were utilized for further fabrication of green articles by slip casting.
