| Physico-chemical properties of some Indian bentonites were systematically
studied in view of their wide application in recent years in ceramic industries as
plasticizer, in glazes etc. The study includes the general properties of bentonites
e.g. colour, fracture, sp. gr., hardness, plasticity, pH, sp conductivity, particle size,
soopy touch, swelling, thixotropy and settling behaviour. The bentonites studied
were Bihar, Jaipur, Akli, Hathi-ki-dhani, Rajula and Karauli. Of the bentonites
studied Akli showed maximum fineness, swelling and dry linear shrinkage. Akli
and Hati-ki-dhani appeared to be Na-based bentonite, and Bihar appeared to be a
Ca-based. Jaipur and Karauli did not exhibit the charocteristic properties of
bentonite. |
