Kaolin

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 …

Once chemical activation becomes more intense, kaolinite areas disappear due to the dealumination process. Consequently, the unmasking of the quartz peaks starts. For example, the 453 cm −1 band is slightly diminished compared to other kaolinite peaks due to the around 450 cm −1 Si–O vibrations of kaolinite and quartz coexistence [ 65 ].
