hydrous potassium-aluminum silicate minerals, such as sericite, biotite, lepidolite, muscovite, phlogopite, and vermiculite, with a lamellar structure and a high aspect ratio (ratio of diameter to thickness.... In the substrate, sericite (K0.5-1(Al, Fe, Mg)2(SiAl)4O10(OH)2), iron ions coexist with potassium, magnesium, and aluminum ions to balance the negative charges of lamellar sericite[18]. Therefore, when sericite......
