Kaolinite is a mineral belonging to the group of aluminosilicates. It is commonly referred to as “China Clay” because it was first discovered in Kao-Lin, China. The term kaolin is used to describe a group of relatively common clay minerals dominated by kaolinite and derived primarily from the alteration of alkali feldspar and micas.Kaolin is a white, soft, plastic

· 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.
