substitution of [Si.sup.4+] by [Al.sup.3] + leads to a net negative surface charges that are compensated by an interlayer of exchangeable hydrated cations ([Ca.sup.2+], [Mg.sup.2+], [Cu.sup.2+], [Na.sup.+], and [H.sup.+]) .

substitution of silicon in the erionite-like structure [AIPO.sub.4]-17 and acidity of SAPO-17.
This phenomenon was presumably due to the reason that Mg2+ was generally replaced by Co2+ through isomorphous
substitution to form Co-O2 octahedron, which increased the distortion degree of the system, leading the hydrogen bonding and electrostatic force between the subject and object decrease gradually, and the absolute value of the binding energy decreased, so the system stability decreased.
One very beneficial consequence of such attention would be to distance Phelan's model from the position immanent in Chatman's scheme, which is to conceive of fictionality and literature as isomorphous
The dispersion of clay particles has been attributed to the disposition of the clay mineral to isomorphous
substitution which influences cation ion exchange and the charge potentials at the clay broken edges in relation to hydroxyl ion dissociation .
During the process of cement hydration, heavy metals eventually settled in the cement hydration products in the form of hydroxide or complex by reacting with cement by means of the physical cementing effect, chemical absorption, isomorphous
replacement, and complex precipitation.
For the Cu-Ni alloy, only one peak is present for each reflection because the Cu-Ni alloy is an isomorphous
binary alloy, which means the two metals are completely soluble in each other and have one type of crystal structure (fcc) with little to no strain .

Deoxidized form Pb was produced on the surface of Fe-oxyhydroxides and Mn-oxyhydroxides or lied in the structures of Fe-oxyhydroxides and Mn-oxyhydroxides by isomorphous
replacement of Fe and Mn elements .
substitutions of [Si.sup.4+] for [Al.sup.3+] in the tetrahedral lattice and [Al.sup.3+] for [Mg.sup.2+] in the octahedral sheet cause an excess of negative charges within montmorillonite layers.
Bentonite is composed of two tetrahedrally coordinated sheets of silicon ions surrounding an octahedrally coordinated sheet of aluminum ions, the isomorphous
substitution of [Al.sup.3+] for [Si.sup.4+] in the tetrahedral layer and [Mg.sup.2+] or [Fe.sup.3+] for [Al.sup.3+] in the octahedral layer results in a net negative surface charge on the layer, which makes it hold its physical and chemical properties, i.e., large specific surface area, cation exchange capacity, and adsorptive affinity for organic and inorganic ions [29, 30].
