Lightening the clay (II)

  According to the previous post, tetrahedral and octahedral sheets combine to form layers, and we can find two main types of clay structures: structure 1:1 (one tetrahedron sheet and one octahedral sheet) and 2:1 (two tetrahedral sheets and one octahedral sheet). The basic structure of clays is this: Substitutions between cations may occur in the tetrahedral and octahedral sheets, resulting ...[Read More]
