    A light yellow colored bentonite clay mineral obtained from India is studied. X ray diffraction (XRD) studies are suggesting that Fe2O3, Al2O3, quartz and Ca bentonite phases are present in the compound. Ca-bentonite is the major constituent and its unit cell is monoclinic with a=5.16, b=8.798, c=9.347Å and β=100.46°. Internal structure studied using Transimission electron microscope (TEM) suggests that the clay consists of iron oxide, aluminium oxide, quartz, Ca bentonite. Tetrahedral and octahedral layers are present. Fe3+ is present in the location of Al3+ in the unit cell of Ca-bentonite. Electron paramagnetic resonance (EPR) results indicate that the unit cell of the crystal contains Fe(III), and its g values are found to be 4.19 and 2.13. IR studies are indicating that the presence of silicate and h.. Read More»
