During isomorphous substitution within the clay, two cations replaceable and replacing must have ionic radii within the range of 0 - 15%.
The process of replacing one structural cation for another of similar size is known as isomorphic substitution. This replacement represents the primary source of both negative and positive charges in clay minerals.
