Abstract
Six Indian clays werr srparated into several fractŁons according. to their particle
sizes by gravity and centrifugal sed1~mentation methods and the chemical and
mineralogical compositions of the fractz~ons wer.e strudved by carryin,Ł: out DT A, bee
measurement, chemical and X-ray analysis and electro-oehemical mPaSiurem,ents.
Rajmahal clay contains only kaolinite in thP fractions below 2 size whereas t!he fraction
above 10 fl size contains an appreciablt! amount of quar
