| Abstract |
| Physicochemical and mineralogical characteristics of different
types of clays, available as overburden in lignite deposit at
Rajpardi village in Bharuch district in Gujarat were studied
with a view to finding out their possible utilisation as replacements
of conventional plastic clays in the manufacture of
traditional ceramic products.
The studies included plastic and dry properties, particle
size distribution, chemical analyses, XRD, DTA as well as
ceramic properties on the specimens fired at different experimental
temperatures. The results showed that the clays were
highly plastic in nature as compared to the traditional plastic
clays and contained predominantly kaolinite minerals associated
with illite/muscovite as minor minerals. |
