| The mode of fabrication of porous ceramic cups of different
compositions and the role of processing variables, relevant
in this context, have been highlighted. The significance of
the consistency of slip and the characterisation of plaster
mould with respect to ensuring the quality of cast products
have been dwelt upon. The nature, amount and distribution
of pores and the mode of their evaluation were also
discussed.
An overall effort of the investigation was to indicate
the important features considered significant for application
of porous ceramic wares in the tensiometer with special
reference to agro industry. The mechanism of pore function
and soil water tension in this particular application
have been elaborated. The criteria of selection of these
wares for satisfactory application, and the performance
of the products developed at CGCRI were indicated. |
