| 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. |
