Finally, bone china is the toughest and most refined kind of porcelain. Made from a mix of bone ash, kaolin, and a feldspathic material, it's vitrified and has a translucent surface. The laborious crafting method and the higher cost of the raw materials make bone china the most expensive type of porcelain.Kaolin, or 'china clay' as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape, and chemical inertness.

Kaolin or china clay is a mixture of different minerals. Its main component is kaolinite; in addition, it frequently contains quartz, mica, feldspar, illite, and montmorillonite. Kaolinite is made up of tiny sheets of triclinic crystals with pseudohexagonal morphology. It is formed by rock weathering. It has some cation exchange capacity.Analysis of the SEM images of PEI-CS (Fig. 1(a)) revealed the presence of a smooth layered structure, while analysis of the SEM images recorded for Ce-UIO-66 (Fig. 1(b)) showed the presence of an agglomerated and deformed octahedron (Stawowy et al., 2019).We also observed that the surface morphology of PEI-CS/Ce-UIO-66 (Fig. 1(c)) …
