| Ball-milled Kerala beach sand sillimanite could be conveniently slipcast
in an alkaline liquid medium to form useful refractory shapes
like thermoelement supports, thermocouple sheaths and melting crucibles.
The results of chemical analysis, particle size distribution of the
ball-mill ground material, the pH-relative viscosity relationship using
some deflocculants and a Mariott tube viscometer and the fired properties
of well-dispersed, slip-cast sillimanite samples have been
presented. It was observed that dense slip-cast sillimanite refractory
wares could be obtained by a suitable treatment of the material. |
