STUDY OF EGYPTIAN BENTONITE BY X-RAY DIFFRACTION METHOD.

Newly discovered Egyptian bentonite was subjected to detailed methods of x-ray diffraction analyses. Oriented aggregate method was used in the preparation of the sample for the examination of clays. The advantage of this method is that the enhancement of diagnostic reflections allows them to be seen when the mineral is present in small proportions. X-ray quantitative analysis was carried out using internal standard method. The raw mineral was composed of bentonite clay and free silica.
