In summary, two methods (M-1 and M-2) were developed and compared to synthesize kaolinite from K-feldspar powder. The kaolinite by M-1 method showed uniform plate-like morphology with the thickness of 35–45 nm. Kaolinite samples synthesized by M-2 method resulted in plate-like sheets with thickness of around 14 nm.
