Crystallinity variations in kaolinite induced by grinding ...

Kaolinite samples treated with uniaxial pressures higher than 0.1 GPa or grinding times greater than 0.3 h show changes in their crystallinity. These changes are easily detected by the X-ray diffraction (XRD) technique and can be quantified from Hinckley (HI), Lietard (R2) and also reference intensity ratio (RIR) index studies. The sensitivity of these indices to the …
