Bentonite (Bent) is a non-metallic mineral with montmorillonite (Mnt) as the main mineral component. Mnt is a layered aluminosilicate with a two-dimensional nanosheet structure. Its crystal structure is a monoclinic 2:1 layered silicate formed by two Si–O tetrahedral sheets encompassing an Al-O (OH) or Mg-O (OH) octahedral sheet.
