Notes:
The effect of ionic size of each cation, Mg, Al, and Si, on the thermal expansion of cordierite, Mg2Al4Si5O18, was systematically investigated by using molecular dynamics simulations. The cell parameter and the thermal expansion are influenced by the ionic size. The ionic size of Al/Si ion has an opposite effect on the thermal expansion along the c-axis to that of Mg ion, i.e., the negative thermal expansion along the c-axis shifts to positive expansion with increasing ionic size of Mg ion and with decreasing ionic size of Al/Si ion.
