| Abstract |
| The physico-chemical properties of kaolinised granites occurring
in abundance near Darugiri area of East Garo Hills, Meghalaya
were studied with a view to finding out their various possible
industrial applications. The study was conducted on the washed
fractions ofthe two clays marked No.1 and No.2, as obtained by
levigation. The investigation included the formulation of various
types of ceramic products like porcelain, stoneware, earthenware
and wall tile and finding out their fired properties at temperatures
of 1100°, 1160°, 1205°, 1250°, 1300° and 1350°C. The
washed clays (Grade I) were also studied for their suitability in
paper, textile, rubber and insecticide industries. The results
indicated that the clay No. 1 in particular was suitable for all the
industries mentioned above. The clay No. 2 was also found
suitable for making ceramic products where fired colour is of
little importance. It can also be utilized in other clay based
industries for products of inferior type. |
