| Mineralogical compositions of five plastic fire clays, viz. Mohuamilan,
Chittorpur, Barachatarma, Neyveli and Badampahar, have been
determined by chemical analysis and X-ray diffraction studies on
active clay components ( < 1,.. e.s.d.). X-ray examination was done
before and after heat-treatment of clays at 600° and 1025°C, The
results indicated that the dominant mineral present in all the clays
belonged to the Kandite group. Moliuamilan and Chittorpur clays
were well crystallized kaolinite. mite was found to be present in
small amount in Neyveli and Badampahar clays. Non-clay minerals
of varying nature in varying proportions were present in all the clays. |
