The process by which clay is formed significantly influences the quality of kaolin by affecting the concentration of kaolinite and impurities. This, in turn, determines its suitability for various industrial purposes. Kaolinite, with the chemical formula Si2Al2O5(OH)4, is the principal mineral in kaolin. It has a molar mass of 258.07 g/mol and forms pseudohexagonal triclinic crystals with distinct physical properties .
